Flying as a passenger I have no trouble with, it's just trying to understand how these complicated dials work.
Well, don't.
Don't try to understand.
The dials you need, what they display, and how to interpret them will be explained as you learn.
The first lesson is usually titled "air experience", and that's all it is. Lesson two "effects of controls" is often introduced as part of this lesson.
Learning to fly is rather holistic, yet performed in a sort-of modular fashion. It will take several lessons, and then several hours after that, to start to get the hang of it. Be content that there will be a lot going on that you have no idea about, and just enjoy the lesson for what it is.
It's a lesson, not a test.
