Xbox Series did well at first (at least in the US and UK) because of PS5 shortages and that there were some people who were going to buy the console no matter what.
Xbox One did well enough early on but Microsoft made some changes that ensured it sailed past 50 million units (closer to 60 million units)
As a console, Microsoft gave up on Xbox Series probably around early to mid 2023. Hardware sales have plummeted because Microsoft acts like they don't give a darn, so why should customers?
