Does she sound like she is really ?

So i saw this girl at the library a few days ago. I had seen her around school also. I tried talking to her but she was really rude to say the least lol. She basically acted like she didn't want to talk to me. I ended up seeing her the next day and so i went up and talked to her again. But this time i kinda got past her outter shell and she started actually talking to me. We were reading each others writing. And she told me some personal stuff. After we talked for a bit she ended up telling me that she liked black guys. Then she told me she was a ... She didn't say anything else about it after that. So idk if she was joking. We laughed about it but idk. Later when we were in the library another guy tried to hit on her and she told him she was a too. So idk. Does she sound like she is really lez? Or was she joking?
