how good do you have to be to play college golf/professional golf?

im 15 and im going to be a sophomore next year. This is my first summer playing golf, i've been out like 20 times and i shoot in the mid to high 80s. Given the fact that ive never been in junior golf and im just figuring out my game i like to think im alright. Next year i will be trying out for my schools golf team and probably junior golf so i hope by the end of it ill be able to shoot in the mid-high 70s. I really want to carry this into college and maybe if somehow i become really good and really consistent i could join like a small golf tour. i would like your feedback on what you think i'd have to do to accomplish these things, THANKS!
