I’ll add a quick explanation of Bernoulli’s principle since it is so often misrepresented. All he did was restate conservation of mechanical energy in terms of fluid motion.

When you stretch a rubber band, your work of stretching it is captured as potential energy within the elastic. When you let it fling off your finger, that potential energy is used to put the band into motion. The potential is transferred into kinetic energy.

Bernoulli is simply saying for fluid flow, that when pressure is high velocity is low and vice versa. It’s very obvious if you think about it. If the flow is speeding up then the pressure must be dropping. Why else would an air molecule accelerate. The pressure difference is pushing it. And likewise, the motion of a fluid as it flows and swirls around an object like a wing is creating pressure differences all around that object. You can measure the pressure anywhere along the surface by simply poking a small hole and attaching a pressure gage. When you add up the total effect you get lift, drag, and moment (twist).

Airfoil surfaces (wings) are just shapes chosen because they generate higher overall pressure differences (lift) with lower amounts of waste (drag and twist).

Hope this helps demystify fluid dynamics.
