Caught stealing from Walmart?

I'm a minor and was caught stealing from Walmart. Don't tell me it was dumb, I know. I had A LOT of stuff. Probably 100-150 dollars worth. My mum said they told her they weren't pressing charges and I would just have to pay restitution and I would receive a letter about that in the mail. Does that mean I'll just have to pay for what I took? Or will there be extra charges I'll have to pay for, like fines? And since they didn't press charges and the police didn't come or anything does that mean I don't have to go to court? I am young and it is my first time.
