P90x question- will this work for me?

I used to be, admittedly, a fat slob. At the age of 16 i weighed 315 pounds and i would sit at home and worry every day when i was gonna die...but then i something changed and i decided to join wrestling, and today im 18 and i weigh 220 pounds, and im feeling better than ever. But my question is, if i do p90x, is it even possible to get abs with how much extra skin id have? like, can i ever be defined if i have extra skin? I dont wanna have to get a surgery and i really like how i feel after i do p90x
