Eh, I wouldn't consider that canon since I think he is just roughly estimating, not going on anything the showrunners told him.
Matt being 28 actually conflicts with canon, since he said Stick had been gone for twenty years, and we know he at least nine when he met Stick. He could be 29, but only if he learned braille and did all his training with Stick in less than one year, which seems unlikely.
