An "unlikely" situation or event is one that doesn't make sense given what we know. You might hear someone say something like, "I don't think it's likely they'll meet up tonight, but let's see how things go."
When people talk about unlikely events, they're usually using the word in a way that means unexpected or hard to believe. We often use it when discussing plans or situations and wonder if everything will come together as hoped for.
