Well, yeah, the clues point to Ozpin being over 80 years old.

The color naming tradition started from a war that ended almost 80 years ago, and Monty said that every single character in the show follows the color naming rule except Ozpin "for reasons."

Ozpin doesn't follow the rule because he was born before the tradition got started almost 80 years ago.
