It is doubtful to hear that a player can enjoy losing, no one likes to lose, losing always brings disappointment, even if the bet amount is insignificant for the player. Another thing is if for a player gambling is a way to distract himself from other concerns, but this is definitely not entertainment, it is a search for stronger emotions, that can switch attention to something else, for a while. And those players who can earn money in gambling are very few, I think only a few percent of the total number of players.
Players who use gambling to forget their current life situation are like some alcoholics. They may end up in compulsive gambling because they wouldn't want to face reality. Being this type of gambler can be very risky. Yet, many players fall into this category and quickly get disappointed when gambling isn't favorable. Imagine if they begin to feel sad over their losses. That means the player won't have any other activity to run to when having a bad day.
That's why I always say that you can't gamble if everything is bad in life. You need to deal with problems and solve them, not run away from them. Yes, casinos try to convince the player that by playing he can win a huge amount of money, and thus solve all his problems, but the chance is so small that it is stupid to believe in it. I think that all problems can be solved if you admit them and try to somehow discuss them with your loved ones. They will help with advice, and running away to the casino, spending your last money is a decision of cowardly people.
