Actually, she isn't mentioning her looks, but her appearence. Not so much, look at how HOT I am, but I don't LOOK like the idea of a gamer chick.
This could just mean she wears skirts, dresses, has a hello kitty purse, etc...
Sterotype city ahead:
There is (wrongly) a percieved impression what a "Gamer Chick" looks like. It not the most flattering picture (of course niether is the "Gamer Guy" sterotype. Watch X-Play, G4, E! or any show on TV when the actually cover Gen Con, Orgins, E-3. While they tend to cover it from a "Here is the Forgotten Realms, lets see what Video Games are coming out for it this year!" They also walk around with a mic & talk to people men & women. You'll notice that the women fall into 2 categories "Booth Babe" and "Gamer Chick" Booth Babe being some model paid to hang out in skimpy clothing for the day. Gamer Chick being well, a female version of the male sterotype.
In effect, girls who aren't bookish, eyeglass wearing types shouldn't be gamers.
It isn't a good sterotype (heck, it ain't even remotely close to reality), but it is there.
So just because she kkeps refereing to her appearence doesn't mean she expects Playboy to give her a call, it probablly refers more to her mannerisms, dress, & other elemements more associated with "Style" than with Physical Appearence. Comliness vs Charisma if you will.
