Of course, every parent has a different perspective and response every time they see or face a problem, I see that your parents are quite different, which as you said you thought they would scold you for being caught gambling but apparently the assumption was wrong. But to be honest here I see your parents are quite understanding, they don't scold you because maybe they know you are a big boy and should be able to think to distinguish what is good and what is bad, I am quite impressed with the advice conveyed by your parents. Instead of scolding you they responded with a suggestion that you can consider, that's right, it doesn't matter if you want to gamble but we have to be responsible gamblers by accepting all the risks involved and also of course with strong self-control so that you don't go too far into gambling.
Your parental reply observation is insightful. It shows their comprehension of human behavior and gambling addiction. Not everyone reacts to aggression. Gentle nudges and understanding are often needed, especially if the person is grown and can tell right from wrong. Responsibility and self-control are key in online gaming. Solution layers are needed for this problem. More people seeing things as clearly as you do might help break addiction's shackles.
