I hear that sound byte (bite?) here a lot. It does not seem to be true based on the news I read. Perhaps you have better sources than I. From what I see, 20 out of 1,083 NCAA schools made money on sports. The other 1,063 lost money.

Only 24 FBS schools generated more revenue than they
spent in 2014, according to the NCAA Revenues and
Expenses of Division I Intercollegiate Athletics Programs
Report. That figure jumped from 20 schools in 2013, but
it has remained relatively consistent through the past
decade.
Don't forget to account for scholarships. You are giving free tuition to the football team, ladies soccer team, lacrosse team, ladies cross country, swimming, etc. etc. etc.

Only two sports were profitable at FBS schools, according
to the report. Football programs netted a median profit
of slightly more than $3 million and men’s basketball
netted a median $340,000. But the profits at most schools
quickly vanished after paying for a long list of other
intercollegiate teams, all of which lose money. The
median loss among of athletic departments was $11.6 million.
