That is an excellent point; it might be tough to tell if someone is suffering from a gambling addiction especially if you don't know them well. However, there are several warning indicators to look out for, such as abrupt behavioural changes, unexplained financial difficulties, or becoming more secretive or evasive. If you feel that someone you know is battling with a gambling addiction, approach them with compassion and offer help.
The people that keeps complaining of becoming addicted to gambling need to check themselves and see if they are doing the right thing that would guarantee them to make money rather then becoming addicted to gambling. Gambling can be a good way to make free money so with that one need to be very careful on the kind of decisions we are making for us to keep seeing results that would benefit us as gamblers. To keep getting good results as gamblers, it is mandatory for one to keep upgrading and updating strategy that would last longer with more subtle way to bet without going extra miles to seek for funds to play games.
One thing "gambling is not a place to earn", I understand that you can win in any type of gambling such as sports betting for example where your skills and experience can be used as a pretty good tool to generate wins, but the logic is that if gambling can be made a place that definitely earns then many people are rich and there will be no more people who lose? of course, this means that gambling is nothing more than a "possibility" where things will not always be able to go according to what you want.
All wins in gambling are always "coincidental", meaning that you will only win occasionally because the possibility of losing will always lurk you in every session, so please don't build an unreasonable perspective or point of view on gambling, don't conclude that gambling is like having a certainty to produce, Do not focus too much on winning because what is certain is that it will only make you feel more disappointed when it turns out that you lose and usually people who come with goals and hopes for victory are usually less likely for them to be able to accept the fact of defeat which in the end emotions dominate and some out of control actions without rational consideration will occur and lead them to a much worse situation.
