This jives with my experience. Also, the grading I’ve done for various professors (and specifically the interaction that goes along with the grading) has exposed me to a lot of variations on the attitude of “officially, there are no stupid questions… but there are definitely stupid questions, and I’m tired of them.” It’s not ubiquitous, but it’s common enough to make worrying about the prof’s opinion pretty reasonable if you expect them to have any say in your future success beyond the grade you get in their class.
