That's baloney. If someone is remotely interested in strategy games for example (MMOs, Real time strategy or Civ like complex games) they are better run on PCs because of keyboard and mouse. There is also the consumer who has the money to splurge out on a high end GPU and wants to run games at high refresh 4K. And there are old dinosaurs like me who could never get used to controllers, and I tried. Got an Xbox controller for my PC for Elden Ring, couldn't get used to it, switched back to KB/Mouse, finished game easy.
