i believe it but many of them are only second accounts of male gamers who made this account for their wife or girlfriend. i have also 2 accounts on my xbox which have been accounts for girls but both accounts have only some hundred or thousand gamerscore.
pretty much all of my friends have a second account for their wife and those play maybe every few months a round of uno or bomberman and many of them played 1vs100.
so yes, i think it's true but i don't think that you can use this number to plan your future investments because most xbox consoles will be sold to guys who have to like the console and the offerings.
it's like saying that 40% of people who use the expensive sound equipment in some peoples houses are female. it would be probably true but 95% of it was sold to males who decided to buy it because they "needed" it.
