In a Nash Equilibrium, players always achieve the maximum possible profit regardless of the strategies chosen by others.

A Nash Equilibrium is a situation in a game where each player has chosen a strategy, and no player can benefit by changing their strategy while the other players keep theirs the same. This doesn't mean that every player is making the most profit possible; instead, it means that given what others are doing, no one can do better by changing their own choice. For example, imagine two companies deciding on their prices. If both set their prices high, they might earn decent profits, but if one lowers its price while the other keeps it high, the lower-priced company could gain more customers. In this case, they are at a Nash Equilibrium because neither company wants to change its price, even though they might not be maximizing their profits together.
