@Mpat19,
I am not a gambler although I have gambled on a rare occasion.
I guess it is two reasons; common sense and lack of interest. Common sense is I know that the odds are not in my favor, why else would casinos be so profitable? So I realize that the odds are stacked against me so I only gamble what I can afford to lose and what I would deem is worth losing for entertainment purposes.
The second is lack of interest. I only gamble as entertainment and I get bored after about an hour of gambling. So the few times I've gone to a casino, I've played some slots and played roulette and I forget what else. And then it gets kind of boring to me. I honestly get more interest watching those that are gambling.
