EDIT: Or Shukaki being corrupted Suna priest etc. Yes, but Kakashi's statement wasn't entirely wrong. Considering we now know that both the Uchiha Clan and Hyuga Clan's origins are the same, they and their respective dojutsu come from Kaguya Otsutsuki. Also, that was said back in Part 1, that was later retconned. What Sasuke said to Naruto was towards the end of Part 2, and Sasuke may not have known much about tailed beasts initially, but after sneaking to Hagoromo as well as witnessing what Naruto did himself during their battles against Juudara and Kaguya would be the reason behind what he said. Sasukeuzumaki also linked you a source.
