I’m wondering too why they are giving different meanings. Does “go figure” really has different meaning? I’m wondering because when someone says “go figure”, I don’t know w/c one of those meaning are the right one. One says it means “who would have thought”, “go figure it out”, or expression of sarcasm etc…

I think in that context, it means “to find out”.
