It's a way to start the conversation. As for deeper meaning, Sam probably realises now about how her actions hurt Freddie in the past, as she's suffering that kind of pain (by liking someone who doesn't like you back, although Sam piled on by insulting and teasing him about it). With that, she'd guess Freddie wouldn't care about her and wouldn't do anything for her unless Carly asked him.
