Sounds like he is trying to use logic or rationalization to "answer" the issue, when you object to his grades or push him to study.
But his lack of interest in studying doesn't likely come from thinking "I'm going to play cricket & cricketers don't need to study." More likely the LOSING INTEREST part is key, and the comments are simply justifications & reasoning. If he enjoyed the work, he'd be excelling in both areas. Sports & academic learning aren't mutually exclusive. Both pursuits express human capacities & potential. (People grow & develop intellectually, socially, aesthetically, physically & morally.)
In a balanced & positive learning environment, people will develop all the various areas because they are not in conflict, and they're all part of being human. But too often it's NOT positive! I'd think his disinterest signals that things are off-track for him and he's internalized negativity & resistance around learning.
