You are, partially correct. The way lift is generated in reality is similar to what happens with a venturi tube, think of air as a liquid, that cannot be compressed, so, when it goes through the "tube" it is funneled down into a smaller hole from which it started out from, and seeing as it cannot be compressed it MUST move faster in order to keep on moving, so in order for it to move faster it must lower the air pressure surrounding the smaller portion of the funnel, so the speed of the air increases and the air pressure decreases, pleasing Newton's third law. Now, how a wing works, is the top of the wing from the leading edge following the entire chord line, is longer than the bottom of the wing, why you ask? Well, seeing as the air is split into two by the wing, the air has to meet up again at the other side correct? So in order for this to happen the air on the top of the wing, seeing as it must travel a farther distance has to speed up, now if we recall the venturi tube example, when air speeds up, pressure decreases, and now the air pressure is lower on top of the wing than it is on the bottom of the wing, so that means the denser air on the bottom of the wing pushes the wing UP into the area of lower pressure, this is the force that we call LIFT. Now of course the engines provide thrust for us to achieve the air speeds necessary to get the air moving over the wings fast enough, put your example of how the wing is slightly titled up is INCORRECT... for the most part. Now, a stall is what happens when the angle of attack of the wing is so far exceeded that the air no longer moves along a straight line along the wing, but instead it just flows off and creates wake turbulence if my mind serves me correct, this means the two air flows do not meet, and therefore no lift is being created, meaning weight overcomes lift, and the aircraft falls to the ground.
If you want to learn all this fantastic theory of flight, just buy yourself the pilots bible, "From the Ground Up"
You also made me get out of bed and turn my computer on just to respond to this... goddamnit.
This is THE BEST, MUST HAVE book to read cover to cover and know by heart. You can probably find a used one for pretty cheap, although I don't know any pilot who would give their copy up!
I don't know what the laws are like outside of Canada but up here you need to take ground school to get your PPL, you can't just challenege the exam AFAIK.
Copypasta'd from another post I wrote:
I'm almost done ground school in Ontario. We use From The Ground Up for everything. It's the aviation bible. There are other books that will go into more detail with certain elements like human factors and how altitude, air pressure and g-forces affect your body but From The Ground Up will cover it in enough detail to pass the exam. Let me go dig up my receipt and I'll get some more links for you.

EDIT2: You should know that getting your PPL (in Canada anyway) will cost around $10,000. I don't have that money either because I just finished university but I was able to find enough for ground school. I believe that you have 2 years to finish the flight part of the PPL training after writing the written exam and only 1 year to finish the written part after finishing the flight exam. However, you do not have to take the written exam once you are done ground school and your ground school never expires. Obviously, it is best if you can work on both parts of the PPL at the same time. I can't right now but in 2 weeks I'll be done ground school and won't have to worry about that again. Although, I'm hoping to join the air force and receive proper flight training with them so my plan doesn't work for everyone.
From the Ground Up. Probably the greatest textbook for recreational pilots. Covers pretty much everything related to flight, from weather prediction, to radionavigation, to engine construction. Probably not exactly the kind of book one would expect to see in a thread like this, but I am sure the other pilots on reddit would agree with me that it's one of the best books in the discipline.
Depends how much knowledge you're starting with. There are plenty of books. And lots of simulation software. I'm pretty sure you can even take classes, including the official ground school classes, and even flying lessons. The only age limit is on actually getting your license to fly solo, you can still fly dual (With an instructor) at any age. Of course, this gets expensive, and young age tends to limit your budget unless your parents are very supportive and generous.
That said I would say start with books and software. For books, assuming you are in the USA, the FAA publishes lots of free resources and here are some other useful suggestions. I am also a fan of From The Ground Up which is actually used as the official training manual in Canada (but this is the US edition).
For software, either Microsoft Flight Simulator or X-Plane are excellent choices. Once you have a little more experience, both can connect to the VATSIM network, which is a group of volunteer air traffic controllers who strive to provide as realistic as possible radio control environment, flight tracking, and navigation services to simulator pilots. The DCS series is also worthy of consideration, despite being combat focused, as it contains by far the most detailed simulation of all the boring and usually forgettable details that you will have to know when you actually climb into an airplane. You can easily spend a few hours just learning where all the controls and switches are, before you even figure out how to follow the checklist, nevermind start the engines.
Finally, if all that's a little bit too intensely realistic for you, or you're still just struggling with the basics, maybe look at something like SimplePlanes or Kerbal Space Program.
Very classy plane. I believe its on the cover of my FTGU (from the ground up)
Obviously I'm commenting way after this is relevant, but I watched about half of the video and this guy has no idea about any airspace regulation at all and really underestimates the hazards of hitting a drone with a plane. 300 feet? That's class G airspace and is the minimum AGL altitude planes must fly. Controlled airspace is around airports and the distance and altitude varies depending on size.
Air strikes can cause damage which will cause planes to undergo documented certified mechanical checks. It's a serious problem.
He also seems to think watching the feed from the drone is better than seeing it. That's the dumbest thing I've ever heard. It doesn't matter which way the drone is facing, it matters where it is, and what it is near.
I agree that a lot of the legislation is dumb, or at least requires some nuance in how it is interpreted, but he vastly understates the problems that flying a drone in regulated airspace can cause because he doesn't know what it is. If he's so confused he should pick up a copy of From the Ground Up.
