This shows with some fluctuations that after 2010 there was a marked increase: https://www.statista.com/statistics/232383/gender-split-of-us-computer-and-video-gamers/#:~:text=The%20statistic%20shows%20the%20gender,increase%20over%20the%20previous%20year.&text=The%20global%20gaming%20industry%20has,fast%20pace%20in%20recent%20years.
Of course the issue with this statistic is that it seems to only take into account the people who have played some video game, whereas some other statistics seem to imply there is a much more significant gap in people who identify as gamers, which is shrinking too. But yeah, the divide before 2010 was greater in general, not that it was as big a deal as they pretend anyways.
