It depends how the other person says the word. If they say it using a matter of fact tone, then they are just agreeing with you. If they drag it out or say it sarcastically, then they are expressing doubt over what you just said.
Sarcastic example:
Person 1: "I can jump two stories without getting hurt."
Person 2: "Sure... and the sky is green too!"
Straight example:
Person 1: "Want to go to the party with us?"
Person 2: "Sure. We will have so much fun!"
