No surprise here. I taught in a parochial school known for sports, this was the pattern. White suburban kids' parents paid tuition and sports fees. A large percentage of inner city kids were recruited 'on scholarship', even though recruiting is against the rules. They were brought in to play sports. Tuition was magically paid from a variety of funds, mostly coming from alumni. The suburban kids typically got less playing time after paying their own way. Some of them figured it out, and if sports mattered enough to them, they transferred elsewhere. I taught a lot of those 'scholarship' students. A few were decent students, but most were barely literate kids who occupied the lowest track classes. You couldn't fail them without a pile of documentation. Most teachers didn't bother; they just lowered the standards. It's ultimately unfair to everyone.
