For those who make gambling to make money, this is a very ridiculous thing and this will be very detrimental for them, they can even spend all their assets on gambling. I agree with you if we think of gambling as a place to seek entertainment, this will benefit us if we experience victory and we can accept it if we experience defeat.
If someone positions gambling to get additional income from each bet then you behave badly in handling your gambling activities, the effect will bring all other finances to gambling and you cannot control yourself for every bet that has been placed in gambling. However, if we place gambling only for entertainment then we will not always be active in gambling games but only for betting on sports teams or favorite fighters, they also use the minimum betting funds because they are not aiming to get profit from the bet, they also anticipate losses if the results the bet didn't live up to expectations and they won't regret it if they lose from gambling.
