If you have the money to fund your betting a consistent betting will make you to win more in the gambling, I know very well that gambling is all about your decision and understanding, so if you want to be addicted in gambling it depends your decisions and if you don't want to be addicted in the gambling it also depends on your decisions in gambling, so we need to be careful for gambling and make use of our wisdom when we gamble, people who consistent gamblers they are not addicted one, because they make profit and also lose on the process, so they don't lose often.
You mentioned that a person can benefit from gambling regularly, but you did not mention how much they lose. How can you say whether a regular gambler is addicted to gambling? Is the amount of money you are spending on gambling unnecessary for you?
If you know the general rules of gambling, you are aware that spending a small part of your total earnings on gambling could be a sound decision. However, for regular gambling, is the amount of money required just a small portion of your earnings, or will you gamble everything you have? I believe gambling is good when you have nothing else to do, and gambling at that time prevents you from wasting time. Gambling beyond your means is nothing but a waste of time and money.
