If it suddenly looks there's a lot of trans fiction out there? Oops, guess there are a lot more trans people in the world than anyone thought.
Once I talked to a guy, whose tactic aimed to make game developers think there are more Linux users than there are - and therefore, that Linux is a profitable market - was to buy as many games as many times as he saw fit, therefore, as if pounding his wallet against the wall. In other terms, he thought he could perhaps hack or bribe the reality this way - the reality of big picture statistics. But in the end, I think it was just a heavy consumerist agenda.
It is unnecessarily true that a lot of "gender" themed games on itch mean there are a lot of "gender" people out there in the world. It means that "gender" people tend to be a lot more active on itch, than they are perhaps on other comparable platforms, as well as, that itch is popular among "gender" developers, for whatever the reason, which in turn could be interesting to discover "why" independently.
