Three lights came on my dash, what would this mean?

I have a 01 Alero... It's not every time I drive my car, but often the "Service vehicle soon", "Anti lock" and "Trac off" lights come on. I'd ume maybe it's a sign I need new breaks. I've had the car 2 years now and never put new breaks on it. Could there be any other problems? Anyone kow for sure the issue? I don't wanna call anywhere yet. I just spent a crap ton of money getting my wisdom teeth out, so I don't have any money to take my car in. Anyone... thank you in advanced!
