Get 2 players stats online without having to replicate anything

I’m trying to figure out if there is a way to get 2 players stats to compare them realtime without having to replicate the client on everything that’s being tracked, Literally, all that I need is a float to compare it while there playing over, say a 10 min timer. So first person to hit say 20 points, wins but they are not in the same map, they’re kinda in separate maps button competing against each other. sorry If the explanation is bad.

Are they still on the same server?

I guess. I dont know or see another way of getting “stats” dedicated server/client
