Basically, the idea that the Bernoulli Principle is the primary factor in airplane lift is a popular lie. For some reason it continues to be broadly taught, so you can't be blamed for not knowing better. The main factor is actually angle of attack--when you hold your hand flat out a car window, tilting the leading edge up drags your hand upwards. That's the core principle of powered flight.
Most conventional planes have the wings installed with an upward angle, so they can achieve lift in level flight. Fighter and aerobatic planes have wings parallel with the fuselage, which means they have to keep the nose slightly up to fly level, but in exchange they can fly upside down almost as well as rightside up.

A few people have posted links already, but here's another that I found simpler and punchier: https://danielmiessler.com/blog/why-planes-fly-what-they-tau...

It makes sense. Can stick you hand out of a window of a moving car and you can feel this effect.
