Eli5 what bernoulli’s principles is and how it works for aviation. Been watching videos about it and still cant wrap my head around it, thanks heaps for any help.

Most of these replies are terrible and dying on the hill of one aspect of lift generation when the facts is there are many different principles at play, all intertwined, which contribute. No one principle alone makes airfoils work.
At the top level both newton and pressure differences add to the lift of a wing.
Addressing newton, yes, the obvious hand out the window effect is there. You can generate lift with a piece of plywood, it’s just INCREDIBLY inefficient.
The “magic” of airfoils occurs on the upper surface. Coanda effect makes the air follow the surface of the wing and turn downward. This turning both creates a force through newton and a pressure difference from a change in velocity. This “magic” is what allows airfoils to work at a reasonably usable amount of efficiency, it’s “free” lift.
BOTH things add to the lift generation if someone tells you it’s one or the other just laugh at them and walk away.
