She isn't your girlfriend. She didn't have an obligation to spend time with you, and while you made an effort to get close to her for the evening, that doesn't entitle you to her affection.

First off, the friend zone is bullshit. You didn't get "friendzoned" you got passed up for another guy because you can't dance probably and maybe they have connections you don't know about.
But to answer your question, does that mean you have no shot? Well not really, try to make a move tonight. If you are being as forward as you said she should know you like her, just a matter of if she's interested in you. So make your move, if she isn't she isn't and then you move on and get over it. But you'll be getting rejected, not friendzoned. Get ready for that rejection, get ready to embrace it.
She might be flightly or flaky or not that into or whatever, but if she's Brazilian I'd go for it.
