Despite those factors, PC gamers still use Windows 11 at a higher rate than Windows 10.
What exactly does "use at a higher rate" mean here? By your own numbers, Win 10 is still around 49.4% while Win 11 is at 46.6%. Also since Win 11 is still only 30% of the market, there clearly is some other factor causing this than just 'preference' (ie: new machine turnover causing Win 11 installs to increase).
As well, kinda have to explain the notion of "statistical error" and "sampling error" here. A change of 0.5% over one month falls well within statistical error, especially given how these use statistics are collected. A more meaningful analysis would have been to show Win 10 and Win 11 use rates over time on a graph and see what the trend lines look like.
Win 11 will increase if for no other reason than "people buy upgrades to their hardware and new hardware" - that was kind of one of the reasons for the hardware restrictions (and now the attempt to switch to ARM) - to get people buying new hardware, but that doesn't mean people are happy about it.
