Is it true? if he finds you in a crowd ..

Means he's attracted?
What signs tell you they're interested?

My sure sign is staring and smiling

Eh? I don't know OP, I tend to not wait around for men to 'pick' or 'choose' me in a crowd. It's not a film.

IME in that scenario men tend to go for women that they think they'll have a chance with, or women that look friendly (so they don't get rejected.

A sure sign for me that someone actually likes me in any meaningful and adult way is when they have taken the time to speak to me (like an adult), asked to get to know me better, told me they like me. I'm not really interested, or complimented by, being stared at by another adult who hasn't got enough about them to strike up a respectful conversation.
