Locked eyes with a girl and she smiled at me, is she interested in me?

I initiated eye contact with this really cute girl at school, and we held the eye contact for like 5 seconds. While are eyes were locked, she smiled at me. When she smiled, she had this really big smile and it was super cute. I wasn't even smiling during the eye contact. Does this mean she is interested in me?

Is it attraction? Not interest.
