What does it mean when a guy talks about me to his friends?

Well I like this guy cody* and his best friend told my sister that he's pretty sure cody* likes me.

but I've never talked to or been around codys* best friend so I'm assuming that cody* talks about me around his right?

or am I just completely wrong? and also, what does he mean "he's pretty sure"?

*name change.
