Does She Like Me Even Though Im Younger ?

Im 15 and she's 16. everytime i see her she always says hi and gives me a big hug. whenever im by her she always calls my name and asks me to sit with her. when we were at the basketball game she was feeling all on me. she was rubbing my bak saying y is ur bak so hot. then wen my friend came over to try and giv her a hug she said ask my boyfriend then she gripped my hand in hers and I felt like she liked me after that. Also today this other girl was trying to give me a hug and she said u better not be having does girls pulling u away if u dont wanna go im gone have to whoop dey *** lol. we also always put our arms around eachother. i jus wouldn't think she would be that interested in me becuz of me being younger than her. idk does she like me ?
