Daniel Ahmad has estimated Xbox Series X|S sell in over 8 million as of September 30. Sell in I am fairly certain means shipped and not sold to consumers. Over 8 million could be 8.1m/8.2m/etc. VGChartz sold to consumers are at 7.61 million on October 2. So a gap of 400K+ between shipped and sold.
Seems resonable enough
