Can i still be PROFESSIONAL SINGER IF I CAN'T BELT HIGH NOTES?

I am 16 years old and i really have a difficult time reaching high notes. i was wondering if you can tell me if it's too late (since i'm almost done growing) to try to really extend my higher belting range by a few notes? i can only belt about a "b" note ABOVE middle "c". (almost an octave higher than middle c.) is that even high at all? i want to belt like carrie underwood. lol. thank you for your help! any tips, i would greatly appreciate. please no rude comments. :)
