So if Suna works like Konohagakure then Gaara most definitely became a Chunin, then Jonin. Also the Databook Mini says that Gaara was already 15 when he became Kazekage.

I don't recall Danzo saying that at all. There's literally zero reason why Suna would promote Gaara to a Chunin all of a sudden.
