Schools exist to prepare students for their adult life, and the working world. They’re going to choose an operating system that the students are likely to encounter at their jobs, and elsewhere in their lives.

Most are gonna be 'give me cheapest you got" even if that means buying HS students baby’s 1st computer from ‘Fissure Nice’ (because they aint gonna spend money that can go in their pocket for name brand shit)

They gave them MacBooks, so I’m not sure how you are arriving at this conclusion. School administrators don’t get to pocket any school budget money that they don’t spend on students.
