Yes. If you are never confused, it probably means you are always within the well-known territory. That feels nice, but you probably don’t learn much.
Of course, all of this only works as an approximation. When you keep making non-zero but very small steps forward, you are learning. (That’s basically the ideal of education—this situation won’t happen naturally, but it can be prepared for others, and then it is both educational and pleasant.) And as you said, not all kinds of confusion lead to learning.
