How do most fund their degree?

I'm a first gen college student, so I have absolutely no idea how funding grad school works. I've been accepted to a few schools already so now I can think about funding my degree. I've been working while going to school to pay bills & tuition since my senior year of high school and I really want to finally be able to strictly focus on my academics without worrying about how I'm going to pay tuition or rent or other expenses. It's hard for me to believe that most people just take out loans... How do most fund their degree?
