Somebody recently said that a better comparison for Arena than chess is poker. Poker has a random element and compensating for that random element requires skill. In poker, even very good players lose games with some frequency. But over the course of many games they tend to win more than they lose. The metaphor isn't perfect -- there isn't much split-second decision making or coordination with teammates in poker, but you can definitely make the right or wrong decision depending on what the other players are doing.
Analogies of any kind can only go so far, but they can be useful shorthand for communication.
