Never tired of ballin' so it's on to the next sport
Ballin' generally refers to two things: playing basketball, and spending money.
Ross references the sports meaning of ballin' while actually referring to spending — possibly moving on to the next sports car.
This line could also be a reference to Ross playing college football scholarship to Albany State, and changing sports — going from football to hip-hop.
