The outcome of the game depends on the cards that got dealt to you, and the way you play your cards. It also depends on the cards that got dealt to others, and the way they play their cards.
You cannot do anything about the cards that got dealt to you or to others. You also cannot do anything about the way others play their cards. The only thing in your control is how you play your cards.
Playing your cards well is necessary if you want a positive outcome. But it is not a guarantee since others may be playing better. However, not playing your cards well almost guarantees a negative outcome, because at least some of the others would be playing their cards well.
