I don't know really, maybe you happened to find some people like that, but I'm pretty sure that people who likes anime have played japanese games at some point. (unless you are strictely referring to anime-based games such as Naruto or Dragon Ball, and even those are fairly popular).
Also, I know people that never watch anime nor uses profile pictures related with it, yet they love stuff like final fantasy, zelda, dark souls and a long etc. Like everything in life, there's a wide range of tastes.
