When a girl says she doesn't have an image of the guy she would be attracted to, does she really mean it?

There is a girl I really like, she says she doesn't have a type, she just likes who she likes but I've noticed that she mostly likes white guys and athletic black guys. I'm neither of them. I think she's lying cause she gives clues that she's into those two types of guys, do you think she's lying?
