The gaming community consists of all those who describe themselves as gamers and buy graphics cards to play games.
LOL, right...
Look at gaming from the gaming industry perspective: hardware and software creators who collect the revenue.
First of all, the notion of sticking a discrete graphics card into a PC is pretty new. PC gaming was the new kid on the block. There was already a nascent console gaming industry in 1981 when the IBM PC debuted which didn't have a portfolio of games when it launched but things like VisiCalc, WordStar, etc.
Which leads us to the first device type that you missed: console gaming. NES debuted in 1983. Even today, console gaming generates revenue comparable to PC gaming.
The next gaming device category you missed is mobile console. By itself, this is not a big category but it is still significant when today's primary player is Nintendo Switch Lite and the earlier 3DS. They've sold over 120 million units of the more powerful Nintendo Switch (which is tabulated under Home Console gaming as is the Switch Online service).
But there's one more device category...

See anything you missed?
Do you think the gaming industry doesn't include mobile gaming as part of the community?
Your definition of the gaming community wasn't right twenty years ago and it's even more incorrect today.
Some people can't see the forest for the trees.
I occasionally watch people play games on Twitch and I'm not savvy enough to instantaneously figure out what device the streamer is gaming on. Sometimes it's obvious (Nintendo exclusive titles like the Zelda games), sometimes it's not (Elden Ring or Minecraft for example). If someone configured their iPad to output video, I doubt if I could tell that either from a quick glance.
But regardless of the device the game code is running on, it's all gaming. As a Twitch spectator, it makes no difference to me.
Trust me, AMD doesn't think about gaming as just the people who buy Radeon cards. They'd also include those who buy PS5 and Xbox X/S now.
And Nvidia doesn't think about gaming as just the people who buy GeForce cards. They'd also include Nintendo Switch owners.
And Intel certainly acknowledges the presence of gaming even though their involvement was mostly CPUs and integrated GPUs until a few months ago.
And add companies like Meta/Facebook, Alphabet/Google, Apple, Netflix, Amazon, and others to those whose often large gaming revenue inflows come heavily from mobile platforms.
Do you think EA only thinks of "gaming community" as those individuals who download the PC version of a game from Origin? Like FIFA?
