My brother was actively involved in online gambling casinos and gambling for about three years. During that time, he invested a lot of time and money and he also gained considerable experience with casino games. However after those three years, the result was that he lost most of what he had.
Watching his experience led me to believe that, in the end people who engage in gambling usually end up losing..
I disagree with you because it is not everyone who engage in gambling activities that usually end up losing as you claim, I know of people who have been gambling for decades, and they still win regularly.
What you need to understand is that, how you approach gambling matters. If you see gambling as purely for fun and entertainment, you are likely to stick to budget and you will know when to stop and walk away.
But, if you are gambling for survival or you see gambling as a source of income you are likely to end up losing, because you will never know when to stop and walk away and this type of people usually end up getting themselves addicted to gambling.
