In this case, i think gambling isn't worth to try for newbie considering the risks of losing money and addiction, i think they shouldn't gambling with real money but only for fun/learning purposes.
If you think so, for me it's not that bad and its worth it for newbies to try out gambling but it's better if they are guided by an expert gambler or a person that is already in gambling industry for a longer time. As long they can afford to lose the money that they are going to gamble and they are willing for it, I guess there's no problem for it.
There is a bunch of speculation on how much money would be made with Gambling and the conclusion is usually that there isn't a right answer. People could win and lose if they make the slightest mistake when betting against something.
If you are looking to get into Gambling, I would suggest that you research the type of Gambling it is first. For example; in E-Sports, looking up the type of game the players are involved in is an easier method of winning a bunch of money. The concept is pretty simple to grasp if you realize the things that is within your screen.
There is also a 77% chance of losing, so be ready for that.
Yes playing your specialty like betting in sports for a newbie is good. But we know that newbies wanted to try things out of their curiosity. I just don't get it where you got that 77% of chance of losing. I don't even know how to measure the chances of winning and for a newbie we know that higher chance of losing is there.
