Even when a gambler gambles under control, he is still gaining experience. Experience is gained through repeated practice, not through a gambler's strategy. A gambler should not be talking about having fun while his income is declining. Any strategy that does not help a gambler recover or reduce his losses is not worthwhile.
Sometimes it really doesn’t matter whether you lose in gambling, as long as one gambles with an amount they can afford to lose, knowing fully well that gambling isn’t a guaranteed way to make money or multiply ones income. So even when you lose that money set aside for gambling, it may likely just little or no effect on you.
Again, just like you rightly said, people gain experience from repeated practice, so does that mean that when you keep gambling and losing, and each time you gamble, you always end up in a lose, would you still continue repeating that practice when the only place it lands you is in a loss, or you’d think of changing to a different approach that may likely help you, in not necessarily to recover losses but to at least make you to experience some wins rather than losses all the time.
Because if you keep doing that, and until you decide to change your approach and strategy, you may likely just be experiencing even more losses.
