Question

roll of studant in politics

Answer 1

Everyone in politics should be a "student", in the sense of a willing to learn, willing to ask challenging / critical questions, and preparing themselves to take responsibility for the society that they are becoming important members of.

Obviously, universities tend to concentrate a lot of young people who have this "student" mentality in one place, where they can inspire each other, and with enough spare time that they can participate in activism of various kinds. So students (as in young people officially enrolled on courses) often do a lot of political activism.

But there's no special "role" for them. Everyone should be like that in principle. It's just that for many people, a lot of other life commitments get in the way.
