I think you mean Gambling has a guaranteed loss which is correct because only a few people make profit in gambling and even that's temporary.
Hahaha

In most cases, there are more losers than those who managed to win from gambling. Gamblers who have good control
are capable of moving out from gambling with some decent earnings.
The rest of the times they end up in a loss. The only people making money are the casino owners.
It's not a good business if the house will allow gamblers to beat them, right? The very reason we keep seeing more and more
new gambling sites that are available now, which do offer decent perks.
This is why we should always consider the money we gamble with is already lost so that we can at least enjoy the games we are gambling.
With the mentality like that, you are just doing yourself a favor. As if you try everything and luck would not be at your side, regrets will keep on following you.
The only reason we should gamble should be to enjoy the games and have fun while doing it.
Sparing some time and money to please your desire, as long as you are not exceeding from your set limits, entertainment is being paid.
