When I was in college, we had office hours with the prof and the TAs, we had group study sessions, and private tutors. Or you could ask your friends. All of those required going somewhere at a specific place and time and asking someone else to give up their time for you.
AI gives you a way to get the same help without asking another human. Say of that what you will, but not everyone was comfortable asking other humans for help even back then.
You also have your book and a wealth of online resources, which also don't require interacting with someone, and which have the same information the AI is trained on. Fundamentally nothing is different. We don't see positive outcomes from students using AI as an aid even if hypothetically it could be possible.
