Agree. Gambling is mostly about the luck factor. Even if the strategy and skills can have a role, the luck factor seems to have a bigger role. So, we can't be too optimistic about the possible result in the gambling games. There is no certainty in gambling games, we relies on our luck at that time. Considering this reality, it is true that we can't gamble with the amount of money that we don't afford to lose. The chance to lose money is quite high, so we must use free money only. Sure, for many gamblers, they have the limits for their funds. So, we don't spend the money excessively.
