This overall statistic may make us feel so bad and regret it, as we may think that "if I did not gamble, I'll still have xxxx money and I can use it for other better things"
That largely depends on your general attitude toward gambling
If you are enjoying this activity in a genuine way, you will just consider the money you lost as necessary and required expenses, a payment of sorts. And then your thought would sound like "Man, if I didn't eat and didn't have to buy food, I'd have accumulated so much money by now that I could buy a mountain of better things with it"
On the other hand, if you are in fact looking for profits, and keep on losing year after year, that makes a perfect case for a witty remark by Albert Einstein, who once said that "insanity is doing the same thing over and over again and expecting different results" (or insanity is crediting that witticism to him over and over again as he never said it)
