There is no way one can gamble for fun and don't have small intentions of gambling for money.
But like I said, it has been made clear to the person that gambling is dangerous if you are using it to chase money, that the end result or outcome may be bad. It is easy for newbie gamblers to understand that. So if they gamble and chasing money and lost money often, they will know they have read about not chasing money while gambling is true. Gambling with small amount of money will give you a peace of mind.
If a gambler continues to pursue gambling after being told clearly, it is certainly dangerous for him. It is true, however, that if one gambles in pursuit of money, it will never bring good results, rather he will only lose and never win. Most new gamblers are very inexperienced when it comes to betting, which is why they always end up gambling to make money. But knowing it can destroy a user and player even if they don't know about it, they are not careful about it and at one time lose their money and get mentally broken. But it is best to use small amount of money for peace of mind while gambling, if luck is good in future then eventually you can win more money from small amount of money.
