To determine if there’s a biological advantage you need to look at the representation of trans players relative to the overall population of bio women within Valorant.
It's like if you had said that people above 5 foot 3 are generally better at valorant than compared with people under 5 foot 3, this is a stupid argument if you're just looking at who is seen doing well in gc. 5 foot 3 people may be proportionally better as if only 5% of val pop is below 5 foot 3 but in pro play 10% of players are below 5 foot 3 then there is a potential chance for there to be biological advantages.
I don't necessarily disagree with you but your generalising the success of all trans people off cherry picked data and you have a lack of understanding of proportional statistics.
