I think it's very important to keep telling these things for gamblers to read and think about. There were many really sad stories associated with gambling, and most them happened because people were not treating gambling as something meant for relaxation.
They started with wrong mind and intention to hunt for money from gambling that is not good and even can cause them to be rekted. In addition, they did not gamble responsibly that is warned at landing page of all gambling site. Similar to smoking like on cigarette box, you will see "Smoking causes lung cancer" but at the end, each person is responsible for what (s)he is doing.
I agree with you that if they consider gambling like gaming, they will have better net results. Don't chase for high multipliers and big wins, their net results should be better and not too negative.
To play game in gaming, people are ready to spend big capital to buy items just for fun but with gambling, they spend $10 and want to get not only $10 back but want to make it to $1000.
You don't go to the movie theater with the hopes of making some cash while watching a film, right? Try to treat gambling the same way, and there will be less negative feelings for you in the future.
I agree with you Betwrong.
