It's better not to lose at all.

But with a casino, this is almost inevitable and losing, to one degree or another, awaits every gambler. Sooner or later. Based on statistics and number theory, on which the enrichment of the casino at the expense of its customers is based. The longer you play, the higher the chance of losing your deposit.
I did exactly as you say. After my deposit turned to 0, I never gambled again. If I had continued, then undoubtedly my loss would have been more. This is a mental wagering trap that players most often fall into. To accept and accept the loss is the only way out of this trap.
Can't argue with you here. All players want to win and this is what attracts them to the casino. It can't be otherwise. In order not to lose money, you need only one restraint: from playing in the casino. Never.
I respect your perspective but think it's a rather one-sided view of what gambling represents. Yes, you're right; the odds are indeed stacked in favor of the house. However, gambling is not solely about winning or losing money. For many, it's a form of entertainment, much like going to the movies or dining out. They spend money on these activities fully knowing that they will not get any monetary return, yet they enjoy it. The same applies to gambling when done responsibly. The thrill of playing, socializing, and the possibility, however slim, of a win can provide entertainment value. Promoting complete abstinence from casino play as the only way to protect one's wallet is akin to advocating people stop going to movies to save money. It's not necessarily a wrong approach, but it may not be the most nuanced perspective.
