Possible friend zone help? ?

First I said "you're a pretty cool girl" the she said thanks I think you're a pretty cool kid. What does this mean? We're both 15. She said "kid" instead of guy. Does she only see me as a friend? I took her out on a date, and texted her all day, made her laugh and everything. Am I in the friend zone?

say, i think your hot, want to go get some ice cream. then you will know
