Every lion in the jungle hunting is out there to get food to eat, and this usually don't matter to the lion what other animal have to loose his or her life, provided the lion gets food to eat and satisfy his or her hunger.
Very true, because lion as the king of the jungle must not die of hunger a d to keep his territory secured and endoring for long he must keep his belly filled with food, so survival becomes a most for the Lion in the jungle, and in this case instance, gambling site/ operators are the lions and the gambler become the prey, and for casinos to keep being in the business, their need to keep generating revenue so in this case the revenue is the casinos food and to keep being live and growing their need to keep generating more and more revenue to keep the business going and that is the reason for the various houses edge in casinos.
Applying this to gambling, gamblers, whether an OG gambler or a newbie, usually don't care who loses for them to profit, and this is true because some time, even the gambler in question have lost a huge amount of money, and whoever made profit from that loss (aside from the casino) the gambler does not know.
Some times I use to think that only the casinos benefits from gambler's loses because since gamblers are not playing against themselves, when they lose their game, the staked amount goes to the casinos hot wallet in the case of a cryptocurrency casinos, I haven't seen where gambler complain about losing to another gambler, although indirectly it's same because when gambler A loses and gambler's B wins, the casinos pays out the winning amount from the hot wallet which is made up of gambler loses, so the loser indirectly pays the winner in a technical arrangement.
So, there is nothing to blame or hold even newbies to, even if they realize that money they intend to make from gambling is another person's loss, it doesn't make any difference or changes anything, for in everything including business and trading, someone somewhere is losing while others are profiting, this is how things were designed to work.
Very correct also my man, this is true in any investment its a chain one person loses for the other to gain, and that is the reason we are always encourage to only use an amount that we can afford to lose and still be comfortable gambling, if you see a gambler who lost huge but keeps playing, you should know that he have also won a good amount in previous games and bets.
