Fame in gaming has largely moved into “content creators”. The most famous game developers are almost certainly YouTubers first and game developers second. There are some fairly big channels now that produce memey content about making games in nearly exactly the same way as people make memey content about Minecraft or Fortnite.
I think you may have a point. I don't play Fortnite, but I know who Ninja is, and casual observers of the gaming world pretty much know his name regardless of playing fortnite. (Though he's not a game dev).
It is an interesting trend that players can now become more famous for playing a game than the people that create the game. However I think that's only possible with the advent of user-created content: Minecraft gameplay on YouTube ~2012-2013 was a big driver in Minecraft's popularity and catalyst for mote activity like that. I think gaming culture would have reached this point without Minecraft, but as it stands right now it was the foundation of the massive gaming channels and streaming.
It’s not that unusual that players get famous for playing games rather than developers. Games are much more active way of engaging with media and playing the game is a far more common experience than making it.
Streaming and gaming personalities both pre-date Minecraft but for sure it’s had a massive cultural impact. Particularly in terms of the growth of an audience through all the kids participating.
