Girl's Behavior

Do flirty girls only want attention or does this girl like me?

Hi, there was a girl in my class at university who I have a crush on. One meeting she tells me that she was tired , then I said "oh I see it... in your eyes". Then she tells me that she had no boyfriend and she liked young looking guys (people say I am young looking). Another time, she was talking to her friend so I walked away, then she came to class and told me the guy was just her "friend". Another time, it was end of class in another class, her groupmate left when I walked to her and she tells me "oh he's just my friend's friend". She also invited me to work with her alone on the group project that was 5 man (just me and her) At the start of the next semester, she mentions that her friend is coming to visit her from china, and when I said "oh. ok". She tells me that "he is just a childhood friend, just a friend, my childhood friend. He's not my boyfriend. I don't have a boyfriend.", and then she was flipping her hair at my face/neck... She is quite the aggressive type of girl but I seen her social network, she seems quite flirty with guys and has flirty pics and she wears some revealing clothing like short shorts (pic below). She is smart, good looking, comes from super rich chinese family and is very confident. I am unsure if she tells everyone that she has no boyfriend or only me? Does it seem like she likes me? Any advice from flirty girls? Do flirty girls usually tell every guy she has no bf? Am I just for attention or does she really like me?

This is a pic of her:
