It's closer to 'try not to be attached to specific outcomes'. It's fine to play the game, as long as you don't get so hung up on trying to 'win' that you can't enjoy your life along the way. It's highly unlikely that you'll get to a point where you think that now you've won and can just enjoy, so focusing too much on the game means you will eventually lose - you're not going to live forever. The 'wins' are happening along the way, and if you look, you'll find many of them at times when you're 'losing'.
