Yome is not a canon character. He never appeared in the manga. Dojutsu are very rare, the humans who possess them are only the descendants of the Otsutsuki.
Gojo_God:Yome actually exists in Naruto, she is a sand kunoichi who canonically has dojutsu. (Besides dojutsu is not as rare as you think, there are other dojutsus besides those most portrayed in the anime)
