The amazing thing with this guy is that hes not a faker. Usually these guys learn a few phrases from a language like chinese or japanese and go to the respective part of town where they speak it and try to impress people. This guy actually knows so many languages that he doesnt "speak" them actually, couldnt hold a real comversation but thats not even the point. Knowing a hundred words from a hundred languages is ten thousand words. Plus a bit of grammar and pronounciation plus french for example and probably a few other languages he actually speaks better and you see how this guy is genuinely impressive even tho he doesnt actually "know" every language as thats not what hes trying to do.
