As you said, it is up to the gambler himself if he will take the advice given to him. So it means, he should also bear the consequences of his actions. No one is to blame but himself. And sure, he should not be forced to follow anyone's piece of advice. Because his decision should be at his own will. And thus, he should accept whatever the consequences of his actions.
because gamblers bet on their own, with their own money, the risk must be accepted by themselves. regardless of whether he bets using advice from others or predictions from certain people, the risk is still in the gambler's hand itself.
regarding the advice given by a gambler who is considered more professional makes sense to me. but indeed some gamblers do not like advice that is considered empty talk. but actually advice like that can make the gambler's thinking better in dealing with several situations in gambling.
For sure absolutely gambling is something that before you set out to gamble, you should accept the risk that will come along with it and that is why gambling must be done using the amount you can afford to lose, if you go out of your way to gamble with an amount of money that is way ahead and beyond your capacity, there is high tendency that you will slide into a condition that you won't be able to manage along the line, so for the Safty of your money and you mental and emotional health, you have to bear in mind the risk and the house edge position in gambling because regardless of whatever skill and experience that the gambler may haven.
So the risks will be 100% on the gambler, and losing is a must because that is all the gambling takes because we have to accept the reality that casinos are out for their own business and the system will always be configured to favor the house always.
So there is nothing to State other than the obvious truth that gamblers are always at a high risk all the time as long as their gamble.
