That is the hierarchy of Konoha Village. ANBU can most likely be either Chuunin or Jounin. Sannin are Jiraiya, Tsunade, and Orochimaru. They are only called this because they have achieved legendary status. Sannin is not a title.

Its not complicated. Their are not uber Jounins, or whatever the hell you said. If you still don't get it...you have been watching the anime for too long.
