I think in gambling there is no assurance that we will not going to lose money. If we really don't want to lose money then stop playing gambling. But of course it is a hard decision for those who are already addictive. But in my own opinion, there is no assurance that we will not lose money in terms of gambling.
It is a thought for you who do not gamble,., but for us gamblers to play with caution,, that is the best way for us to minimize losses. It looks like you are not a gambler..
Even gambler or not it is given that we can lose money in playing. There is really no assurance that we cant lose money. In gambling it is best if your lucky that your always winning in the game. Only the owner who got rich here.
