Is Off campus significantly cheaper

Hi guys! i’m starting my first-year at UC San Diego and will be moving in less than a week. I want to ask any continuing students if Off-Campus housing is better and WAYYYY MOREEE cheaper or significantly less than On-campus. Obviously if you’re living with roommates or with other people. Because if not I’m lwk deadass cooked and I don’t know how i’ll continue my studies at UC San Diego 😭. And to be straight up I don’t know how I’ll be paying 12k out-of-pocket for the entire year.
