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.

The idea that lift comes entirely or mostly from pressure differences created by Bernoulli’s principle is a myth.
Most of the lift comes from deflection of airflow via the aerofoil shape and angle of attack, consistent with Newton’s third law. Air flowing past the wing is pushed down, so the wing is pushed up. Think of how it feels to hold your hand out the window of a car.
There are however many different forces at work, including air pressures, which would all need to be included in a detailed calculation of lift (which is well beyond my knowledge).
