Student Athlete/Professional Athlete

Hey everyone just had a question. How much impact does being a division 1 student athlete at an ivy league school have on your applications? Would admissions take that into consideration when looking at my GPA (3.66)? Also, wondering how much impact does being a professional athlete at the youth level have on the application! Have experienced both and transitioned into academics fairly late and would appreciate any feedback! Would I have to write an addendum emphasizing my time as a student athlete/professional?

Thank you!!
