The brother gods might not be on Remnant anymore, though. Qrow said that the gods abandoned Remnant.

"Well, that's the kicker. See, the four gifts to mankind - knowledge, creation, destruction and choice - aren't just metaphorical. Each of them exists in a physical form, left behind by the gods before they abandoned Remnant, and each of them is extraordinarily powerful."

Qrow knows about Ozpin moving on to a new vessel whenever he dies, so why wouldn't he know about Ozpin being the Light God? Unless he decided to keep that detail a secret from RNJR.
