We don't have to deceive ourse when gambling, everything we do have same risk as long as they are activities we participates under in gambling, we may choose to play safe after realizing the risk involved in the kind of betting we are going for, the level of the risk taken is from our own part to choose how far we want to take it, but not that some games are more favourable in luck than the other.
Though the weight of your statement is valid, as the amount of risk is always the same in terms of any gambling activities that we will be participating
the only thing that may add the edge is the knowledge that you have about the game you choose to play.
With that idea, controlling your emotion and managing the amount of money that you are willing to stake can be controlled, and then again, the chance of
winning still depends on the amount of luck you have and the timing that you use quitting your way with a decent amount of profits.
If we don't go to school to be taught how to gamble then it's uncalled for a gambler to be expecting someone to tell him on how to gamble responsibly, if you can't take the risk then don't go for it, gambling is for fun and not for other things we try to make it becomes which are not part of its constituents, we have to control the way we spend money to gambling, the time used as well as the frequency to how we are gambling leaving other things.
