My crush said bye to me. Does that mean anything?

So my crush said “see ya” to me on his way out and he never talks to me. I was the only one out there when he said it and I don’t think he would feel like he needed to say it but I don't know what do you think?
He likes you
He was just being polite
He just wants to be your friend
