I'm in a small gaming clan which plays a (dated) first-person shooter, and our oldest player is in his late 50s. I also know a lot of older people who play mobile games, or online poker, or Wordle. The three groups behave in radically different ways, and trying to understand their consumption is pointless without further segmentation. If you target the mobile gamers with ads about gaming mice they're not going to buy them, our 50-something has approximately zero chance of clicking on an ad for Clash of Clans, and the Wordle players would mostly be insulted by ads for online poker.
Same sort of problem as a survey of "readers" has, where fiction and non-fiction are so different that overall stats are misleading.
