Yes, if we are counting only game consoles, now if we count game studios owned by each company, and they earnings across all platforms, it is a complete different picture.
Microsoft owns PC, and even Valve has forced to emulate Windows/DirectX to have any games on SteamDeck.
The amount of office worker typing Excel sheets on mobile phones is rather tiny.
What matters is where money is, and how much of those games trace back to Microsoft owned studios.
Good example with mobile games though, as it is a good example of Valve's failure to capitalise on 80% of mobile games being run with OpenGL/Vulkan, on a Linux like platform, and yet they have to translate Win32/DirectX, as means to get games on SteamDeck.
