If gambling is a disease then it can be solved by taking a aspirin unfortunately it won't work that way. Its up to that particular person to fix himself up
In my opinion, I don't think gambling is a disease, for me it is a disorder. There are a lot of kinds of diseases nowadays and how you earn them is through bacterias, heriditary, from other people and a lot of ways. In terms of disorder, it might be because of the state you are in before you got the disorder or also it is hereditary. For me gambling addiction is a mental disorder, you don't know that you are prioritizing the wrong thing,you are spending your money endlessly to something that will destroy you in the end.
Gambling addiction is not a disease. It is more related to the greediness nature of human being. The more you think that you want to gain quick money, the more you will play and try your luck with gambling. You might hurt yourself and even your family members if you too much spend in gambling.
