If you’re worried about having an ID, you can just get a state ID like whenhen said. I got one before I was old enough to have a license because I was traveling and my parents wanted me to have an ID.
If you’re worried about not being able to drive, I’m assuming you won’t even have a car to drive so it’s less of an issue. Look up ways to get around with public transportation. If you’re living on campus, you might not even need to use it that much, but it’s always good to know what’s available. Your school may offer free or reduced cost bus/public transit passes. When I was in college, most students didn’t bring cars to campus at all because it was so expensive to park. Most used some form of public transportation. I didn’t have a car all through undergrad (and lived in an area with some but not great public transportation), and I managed just fine.
If you would like to get a license while you are in college, you will need to look up the policies for the state you are in. It is doable if you make a friend who has a car that they are willing to let you practice with and borrow to take the test, but really, there probably won’t be that much of a rush. It’s not a big deal to not have a license, and you can always get your license when if you go home for the summer or some other time.
