Gamblers at their teenage, do many mistakes. But it doesn't mean they are bad. Actually sociaty always treated gamblers as suspicious and so was happen with your newbie. She wasn't sure her momey was stolen or not but suspicious mind force her to believe such thing. actually when it comes to gamblers, people are too quick to judge them without trying to reveal the trusth. Let gamblers have some time figure it out. My perception about them is that, your nephew would grow up soon with hard experience and then he'll set his mind to figure out which is good and bad for him. Until that, give him just one advice is to control himself during gambling, only stake what he can afford as he also said already
Not all the gamblers are the teenagers,with my experience most of the population of the gamblers are from the 40+ age category of gamblers.After the stress from their job at the work,the most seeking entertainment will be the gambling.The gambling is like the drug to satisfy at their 40+ ages,So they will gamble with the money from all their expenses.Most of the experienced gamblers will choose the free money after their spending to their food and their family medical expenses.Because the medical expenses is not the permanent one,the medical free months money can be used by the gamblers on gambling.
A person who is working and has a job and is earning an income either on a monthly or weekly basis will actually have a specific percentage of their salary allocated for their gambling activities if they do it for fun or get some entertainment, and they don't really need to wait for a month or a week when they don't have a certain expense and use the money they have saved from that on gambling, for most people, that isn't what they do if they gamble.
Things like that are done by people who don't earn enough to have a separate budget for their gambling activities, so what they do is they keep looking for days or weeks or months when they can save some money and then use that money for gambling but such people don't really do it just for fun.
People allocate a specific part of their income for gambling, hoping for fun and maybe a big win. However, even when done for entertainment, it's very simple to go from enjoying yourself to picking up bad habits. I believe that extreme caution is essential in this situation. You're correct when you remark that many people save money for gambling after waiting a time. For them, it's not really about having fun, is it? I detect a desire for a financial turnaround, a way out of their financial worries. I entreat such individuals to think twice before acting. I understand it's their choice and their money. But since short-term satisfaction might result in long-term issues, it's usually a good idea to consider long-term stability instead.
