Am I going to juvenile detention?(Juvy)?

About like 2 months ago I sold a friend a knife and he brought it to school but then everyone was getting checked(like alot of people) and so he told be to hold the knife(which i was dumb enough to do) and i got caught with it. So basically i only got possession of knife. The knife was spring isted locking 3 inch blade So today in the mail i got a thing that says i have to go to court. It says Notice of hearing-juvenile delinquency proceeding welfare 602(what does this mean?). Then it says the hearing is the purpose of formal reading of petition, advisement of rights, and plea.(what does this mean?). Then Juvenile wardship petition original 602(a) 01) PC 626.10(a) M.(what does this mean!!!!)...Bottom Line...AM I GOING TO JUVY Seriously!!!
