IMPORTANT!!! Plz helP!?

Okay well a couple of weeks ago I got caught shoplifting from walmart. This was my first offense I was about to get away with 213$ worth of stuff they didn't catch me on camera however the secret shoppers saw me and didn't stop me until I was already about to walk to the parking lot so today I got my ticket which was 150$ but my friend who got caught shoplifting aswell said that there wiLl be another ticket of about 500$ comeing in in about 2 weeks so my question is ....is this true (that ill be gettin another ticket)? Ohh and by the way I'm 15 years old ...
