There’s a scene in the netflix show, Daybreak, where RZA as a narrator explains how eastern warrior culture became popular in the black community. Which is what i thought of reading your question. I couldn’t find a clip but here’s an article about it, and the relevant quote:

“It’s not your fault you want to be a samurai,” says RZA. “See, that’s the economical pressure being expressed as warrior code. It started when young black men couldn’t afford to go to the movies, so we watched kung fu reruns. We found beauty in things that had been neglected.” He explains the socioeconomic forces that raised a whole generation of “blerds,” spinning out into everything from Jim Kelly to The Last Dragon to Kendrick Lamar’s “Kung Fu Kenny” to The Boondocks to Wu-Tang Clan itself.

For a serious answer, as someone who grew up in a family that couldn’t afford cable television. DBZ, Sailor Moon, and Pokémon all aired on network, antenna, televison in the morning before school or after school throughout the 90’s.

So it’s probably a function of income more than race. All the poor white kids I grew up with worshiped those three shows too.
