For the 15th birthday Microsofoft told us some interesting numbers: https://news.xbox.com/en-us/2016/11/15/celebrating-15-years-xbox/
Number of players: 222,468,423
Number of total gaming hours: 100,539,390,670
Number of total multiplayer hours: 29,000,304,183
Number of Achievements unlocked: 32,667,582,157
Gamerscore racked up: 572,605,554,587
Highest Gamerscore: 1,416,465
Number of Xbox Live friendships made: 4,233,891,482
Have they updated some of these cumulative numbers since then? I expected at least some total numbers for the 20th birthday.
Especially the numbers of total gaming hours would be interesting. Two years ago they were showing 4.28 billion game hours per month... so around 50 billion gaming hours per year in 2019 - 2021, probably less in the years 2016 - 2018?
