Helped a girl get something she wanted, without having to pay for it

This girl wanted something, that was not materialistic (for once). While you could say this thing is kind of materialistic it was more about something else that she wanted, and I believe I helped her get it (she won).

I like her. She's gorgeous and nice and funny but I suffer from low confidence so I don't think I would have a shot with her. What do I do?
