All I know is that, in Destiny, when Ironwood was talking to Team RWBY, he told Yang that millions of viewers saw her "injure" Mercury. So, it's possible that Remnant's worldwide population (the tournament was broadcast live to the entire world) is only in the millions, not the billions. How many millions is uncertain. Could be tens or hundreds of millions, for all we know.
