It means ot is the opposite. "No, Frank didn't tell Sarah, it's the other way round. Sarah told Frank." vice versa has a different meaning. It means 2 equal acts. If I say I will teach you English and ask if you will teach me Arabic in exchange, I could say : How about I teach you and vice versa.

here is another example: "so, I have to pick up the dry cleaning, then drop the kids at school". No, it is the other way around - drop the kids first.

"Vice versa" essentially means "the other way around", but is normally only used when you are talking about the equivalence of an inverse relationship: "John loves Jane, and vice versa." "The other way around" can additionally be used in a physical sense, in which case "vice versa" won't really work: "This art has been hung the other way around from what the artist intended."

"It is the other way around" means the same as "Vice versa", but "it is the other way around" can be used in more sentences. "vice versa" requires that there are two items in the sentence that you can swap to reverse the meaning, but "it is the other way around" does not. For example: "science must be at the service of man, and not vice versa". This is a sentence where it makes sense to use "vice versa" because there are two main items that can be swapped. BUT, the sentence could also be written as: "science must be at the service of man, and not the other way around", which means the exact same thing. "It is the other way around" could also mean something is turned around the opposite way. For example: "Is the battery in the right way?" "No, it is the other way around."
