In gambling a gambler will only win one or two games but his loss will be maximum and those who are winning again and again are lucky enough that their wins are more than their loss. Luck will decide how much you will be profitable from gambling and there is nothing to study about gambling and learn about the process of getting success in gambling.
You cannot work hard for gambling because it is assumed that if you are gambling more then your wins will not increase but you will face more difficulties as your bet can be true or false depending on your luck and there is nothing through accepting which you can learn about gambling.
"Maximum" unnecessary word, I don't believe that losses are always maximum in every situation as a gambler, we cannot judge with such convictions.
Gambling is a game of probability of which it is low on the side of Gamblers winning, invariably meaning that Gamblers expect to win based off the chances presented and not luck, if we say luck why then do we analyse, make decision before gambling while not some random bet. There is nothing like luck, though everyone is entitled to there opinion but I would not support such as there is no lucky or unlucky gambler.
Gambling is more of luck and not analysis or decision making, and this is why you see it that a gambler cannot keep on winning but a gambler can keep on losing because luck comes once in a while. I see gambling as a try your luck thing and whoever take it so will accept the outcome of his bet.
We have games that are purely luck like slot machines, but people still hit the jackpot, so what will you call that. It is Sam with every other game that is used for gambling. Sportbet is the same if not a lot of people will be cashing out everyday due to their good analysis. Have you not heard that there is no professional gambler, no one can predict what will happen tomorrow correctly.
