Well, first of all people dont play with eachother on other sides of the world typically. Games are often played within “regions” such as NA west, NA East, Europe, etc.
Even within these regions the distances can still be staggering, however you have to consider how fast communication signals can travel. Lets say the signals travel at about 0.5x the speed of light. That means the signal can go from Nova Scotia, Canada to Los Angeles, USA in about 0.05s
The limiting factor turns out to be the processing speed of the device locally most of the time.
