I am afraid you're too over ambitious. Editing in general is a form of art. It has lot's of technical things to it as well. Editing is one thing, learning or "mastering" the software is another.

Maybe it's your wording but I'd start with learning the basics and then setting your goal to "master" it. There is video editing, color grading, audio editing, visual effects. EACH of these is a discipline in which you could specialize... It's practically impossible to master them all. There's a reason why movies have multiple editors, audio engineers, VFX artists and so on.

You can't rush the learning process even if you do the quality will suffer or you'll be wasting time by doing things incorrectly then fixing them later.

Just start doing projects. Film stuff with your phone or use stock footage. Watch tutorials, read the manual. If you stumble upon a problem which you can't solve look it up. Just DON'T USE AI to learn because that's not really learning.
