How do developers make it possible to render the same map and real-time events to people using different devices and living a thousand miles away?

Well, to some degree, they don’t. A big part of developing a multiplayer game is hiding lag and the discrepancies that are caused by lag.
For things like the map, it’s easy; they send the map to everybody once at the beginning. In many games, this is done prior to the server opening, and happens when players download the game. Since they’re all playing the same game, they have the same maps. When modifications are made, these modifications are shared to the server. Some delay is present, but normally not a gamebreaking amount. However, “gamebreaking” is different for different games. COD requires way less lag than chess.
