It's true, and yet even with a lot of people not being gamers[1]:

> Global videogame revenue is expected to surge 20% to $179.7 billion in 2020, according to IDC data, making the videogame industry a bigger moneymaker than the global movie and North American sports industries combined.

So the fact that there are still lots of people who aren't gamers just means that the video game industry has plenty of room for growth.

the "gaming" industry includes mobile games and things like slot machines, in addition to the big consoles that most people think of.

I think there are more "gamers" than you might think.

Plenty of them are willing to watch people play video games, even if they don't want to play them.
