GMs saying things fail because they're inadequately impressed
I don't necessarily interpret things in the best possible light, but this isn't a binary situation where the alternative is interpreting them in a negative light.
We are pretty much on the same page regarding competence, assuming there's no explicit reason to assume incompetence.
Based on what you've actually said in this thread, as long as you were willing to participate in good faith, I would see no reason not to want you at my table and no reason to think you wouldn't fit in. It's entirely possible that you're not looking for the same things as me in RPGs, but I don't see any reason to believe my GMing style would lead you to feel a loss of agency or as if you're playing mother-may-I, unless you enter the game already convinced that's what it's going to be.
