literal scam bro i hvnt been studying just because of that offer
That's actually scary. From what I've seen online and what my career's adviser told me is they only very very rarely revoke unconditional offers if:
-The course seats get full too quickly and you didn't accept the offer in time.
-You do some sort of academic misconduct or you lied in your application.
-Your grades drop really really significantly than they expected. Like really significantly. And this is normally for more competitive courses.
I want to say you'll be fine. But I think you'll benefit from studying a tiny bit. But don't stress too much.
