The Journal drew these conclusions from a study of several databases and interviews with experts.
Eighty-nine percent of gamblers lost money in a study of 4,222 anonymous users of one online gambling network in Europe that includes games of chance like roulette, blackjack, and slots. In the small set of winners, few won more than $150.
Among the heaviest gamblers, 95% lost money. In this group, big losers outnumbered big winners by 128 to 1.
In another study of 18,000 loyalty card holders at U.S. casinos, only 13.5% ended up winning money.
The odds of winning were better when it came to games of skill like poker, but still most gamblers lost money.
And that's all you need to know when it comes to the investment value of gambling for most people.
