The claim wasn't "originated from video-games" it was "related to games." More broadly, aside from the direct technology terms, most of those are the sort of words that you only encounter in media.

Videogames are a medium that tends to stretch for more words to describe things (as do novels, compared to snappier media like film/music/tv), so it's a very likely point of first exposure for those of us young enough to have grown up with them.
