I'm pretty sure that's dead wrong. Facts notwithstanding, I remember hearing that the majority of Naval Officers come from the Academy. Next up ROTC and OCS fills in the blanks.
Funny, we always heard it was ROTC first, then USNA. It just seemed like USNA was primary because there were 1000 of us from the same school, but ROTC were all from different skools.
My claim comes with data. Sort of:
