xbox is a catch-it-umbrella that includes all the studios bought, and game pass. The xbox hardware sales are beyond appalling[0], $220m a quarter, and it'd be below $1b yearly. That's revenue - the consoles have pretty terrible profit margin by design. (likely negative when it comes to xbox)
Being a console ecosystem owner doesn't work if one doesn't have a console?
Hence why it makes sense to look at their gaming division revenue as a whole: a large part of that revenue is attributable to shipped to date XBox units.
I wouldn't be surprised if most of that revenue is PlayStation. That's why they've been porting their entire catalog over, claimed the end of exclusives etc.
Last I heard the current Xbox generation has sold less than the last, at approximately 30 million. This gives it about 1/3rd the sales of Sony.

You were saying something about not letting facts get in the way of a preferred narrative, I believe?
