It is important to understand that not all participants in gambling games are gamblers. The aim of the "professional gambler," as he is called, is to make money. He can be recognized by deliberate and extremely disciplined wagering. His wagering is systematic and usually limited to infrequent but highly favorable opportunities. The behavior of the professional gambler is highly controlled and usually the result of a studied approach to his chosen game.
