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.
