Is that the Six Forms?
If so, I'd say it's probably not most of them. Seems like a martial art that normally only WG operatives are taught. Yeah, Coby knows one of them, but he was trained personally by a Vice Admiral.
I doubt many of the pirates know any of them unless they possess Luffy's inexplicable ability to learn a complicated martial art move just by watching someone else do it.
I'm sure high level users on both sides have it, I doubt the rank and file do.
