bait post, but i'll entertain a proper answer.
probably? though i'd put many other factors as more significant first.
i don't think the playerbase disparity paints the full picture - polls show that 30% of valorant players are women, so all other things equal, you'd also expect 30% of t1 valorant pros to be women too. clearly not the case, so something else has to be going on.
i think most of the reason is social - studies have shown that men have a disposition to be more aggressive and assertive when pursuing a high level of competition. whether this disparity is biological or social can be left to the experts, but i'd think that this is what results in such a heavy disparity at the highest level of play.
you could also boil it down to gaming being a really toxic space for women - players around might be less supportive or they may be offered less opportunities to improve - its similar to how, oddly enough, professional sports players tend to be born around september - january (since a couple months of development is a huge difference in early ages, meaning sports coaches support them more or pick them for sports teams etc), despite birth month not leading to any biological difference.
biology i'd probably put as the least significant reason. there may be some inherent differences in reaction speeds and dexterity due to hormones, but i don't think it's like traditional sports where strength and speed is everything. women also dominate in challenging sports which prioritise things that suit their biology (gymnastics, for instance), so I don't think the "spirit of competition" is inherently non-present in women.
