In fiction, unique magical abilities can and often are genetic, passed down from parent to child.

For a quick example, Boruto's Dad has entire clans with special Jutsu passed down from generation to generation, like the Byakugan and the Sharingan. Being genetic doesn't make them any less Jutsu than any other Jutsu.

As for the SEW's powers being thanks to Ozpin's magic, it's impossible to say at this point, but the Maidens and the Vaults do prove one thing: Whatever Ozpin does with his magic stays for a very, very, very long time, if not forever. It may change hands, but it doesn't disappear.
