OK, I get it now. "Professor" is just a job title, where each organization can define it and confer it as suits them.
Yes. More specifically, it usually refers to someone who is a member of the faculty at a university. It doesn't necessarily mean they're an instructor.
At research universities, it's actually not all that uncommon for someone to hold the title of professor and not teach. I have a relative in that position. He oversees a research group at a university, which conducts deep statistical analyses of various medical treatments. He is a professor, but he's never taught a class - he entirely does research. He oversees a number of graduate students, but he does not teach.
The point is that Biden isn't suffering from dementia because he described himself as both a professor and having taught in law school. Both of those things are completely accurate. He held the title of professor, and he was a teacher at Widener law school in Delaware back when he was a senator.
