Not only slot games but also other non-slot games are risky and gamblers can lose money because their bets and chances of win or lose depends on randomness, probability and luckiness. All of those contributors, but there are more ones, can not be controlled by gamblers so the risk of win or lose with bet is very uncertain.
We need to be careful playing gambling games. We never know when we win or lose. But the losses will be behind us after we start gambling. If we can be careful, there is nothing to worry about because we can take care of ourselves and avoid mistake. We will not follow our greediness but we control it and not ruin ourselves.
We just need to be aware on the risk on what we are doing and if we deposit the amount we can afford to lose then provably that we won't get any problem even if we are unlucky then we lose our funds.
We can't avoid to commit mistake but what's more important is we are prepared on it and use the money we can afford to lose.
Yeah, being aware of the risk is a must thing that we need to do. But many people lose control once they see their winning. They want to win more so make them continue instead of stopping gambling. It happens to many gamblers so being aware is what we need to have so we know when we must stop gambling.
We can't let ourselves make the same mistake over time. So being aware is really important and we must manage carefully. If we can reduce the big losses, that will be better instead we regret it.
