Personally, I don't believe that those gamblers who are always gambling despite consecutive their losses, are not chasing their losses because if they win back their losses, they wouldn't stop gambling forever. Instead, they'll start thinking of winning big, which becomes a trap to gamblers in order for them to continue playing irrespective of their losses. A gambler that wouldn't let go of his losses, is gambling for profit.
The great tragedy for a gambler is, "He wins once, loses again and again!" And these one or two wins are a trap to ruin their lives. A gambler must be very practical. He must have a lot of common sense and be careful around him. And he cannot be tempted by greed. Greed is the main reason for the destruction of a gambler. So a gambler must be very practical.
