I like a girl in my work. I tried to talk to her she's smiling and even asked questions. when I asked for her number , she just gave her insta inste?

she gave me her Instagram instead and she followed me. I saw her giving her number to a random guy , he's not handsome tho but maybe she's just being nice so i was confident i can get her number but i wasn't. i know it's just our first long Convo but I'm just curious if she's just not interested in me or just want to know me more before she gives her number to me. pls answer my question guys
