Go on Steam, look at the most played games right now, look at the demographics for those games.
Or pick some player profiles at random, count how many girls vs guys you find (very easy to tell with high accuracy just by looking at the games they play, yes there are exceptions but they're actually quite rare, I promise you can get >90% accuracy after you do a few).
Steam user base is at least 3/4 male by user count, probably even more by play time.
Clearing up confusion about a demographic by assuming things about other demographics seems like a bad idea.
Maybe, due to the budget specs, they figure the “cozy gamer” demographic will be their sweet spot. Hence the Stardew Valley video and Cuphead with its retro/nostalgic graphics. The people they showed do seem like they’d fall into that demographic, which would be less concerned with their FPS counts and playing games that don’t stress the system as much, generally speaking.
