I partially agree with you, gambling is indeed an exciting hobby but whether it is not healthy depends on us. Even drinking a lot of colas is not healthy. So anything in excess isn't good.
From my own of understanding of understanding something, i come to know that gambling which everybody is capitalizing that is not good from the way the understand and the way they do explain to people concerning gambling that is not good, but base on your explanation i understand that even though it's a food we consumed daily, having it excessively is very bad and harmful, so therefore i agree with you
