Do you think I have a chance of being famous?

I really want to be an actress and a singer. Not just for fame, because I love it. I am going to take vocal cles and acting cles this month. I've been in 3 plays, one commercial,modeled a few times,been to a casting call once and got a call back but my parents said no.My sister works near the warner bros. studios and she gets to meet many directors/actors/people who make cartoons(like the grim adventures of billy and mandy). I have an aunt who works for the woman who played the mother of lizzie mcguire. The actors studio where I'll take cles recommends it's students to agents and agencies. My dad even made the actual little pieces of metal that leonardo used in the movie inception where he works. My mom even used to work with friends of the band yellowv card. So I have many contacts. What do you think? Do I have a chance?
