Bowling question about possibly going pro?

I am 18 years old, and have been bowling for 7 years, i currently bowl in the saturday youth league, and just finished off the season with 91 games holding a 219 average, i hope to do better in the summer and bring my average even higher because i know i can if i try. I am lefty and have wanted to go pro but dont know if im good enough cuz there are so many bowlers i cant really compare. i bowl in many trnys, and practice on pba/sport shots, just not sure if im as good as i need to be to hopefully make it someday
