When we win money, we break this scheme. In the same way it is broken by theft, robbery, or taxes. If money is obtained for nothing, it loses its value.
Winning money does not mean that the value is lost. In gambling for example the value already comes from the risk that is exchanged between various gamblers. There are some that are betting on the outcome on a game and other that are betting against it. The both side are simply taking risks and some will have to loose in order for others to win and this process is what facilitates the movement of value. And this is Avery different from theft, robbery and the others you mentioned.
