Well-rounded class and well-rounded students aren’t mutually exclusive.
Unless a person is an famous actor or actress, olympic medal winner, celebrity, etc, their pointed-achievement won’t be exceptional. ** Since the OP hasn’t won an international medal clearly her pointed athletic application isn’t enough. **
Lastly there are far too many archetypical profiles: jocks who swims for his HS team and volunteers as a lifeguard; nerds who have won every science fair but never stepped foot on a basketball court. It’s hard to stand-out with a pointed application.
So for the vast majority of applicants–including the OP–being well-rounded is the best strategy for college admissions.
