One other thing of note is that the "Other" category increased by +0.31% , which would include all models of RX 6000 cards combined; This gives you some idea of scale.
But that number is also affected by people buying/trying to game on weird cards overlooked they buy on ebay (like workstation graphics). Also people on uncommon cards will have exited the "other" category as they can get something more popular.
Compare that to something like the GTX 1650, which increased by +0.21%. It is possible, and perhaps even likely, that more gamers have been able to start playing on a GTX 1650 than on any particular RX 6000 model (or on the RTX 3060). I don't think the1650 is even being manufactured right now. Although, I think Nvidia may have started producing that same basic GPU for mining cards.
