If Gambling is for fun then its not wrong but if just spend all your money in gambling like a crazy then it is wrong as it will make you loose everything.
When you really lose everything youve got then you are doing it wrong,many people do it for fun and when they profit its enough for them.
many people are going to gamble with the intention of to having fun.
then they too enjoy and suffered several defeats. somehow all [layers always think you're going to profit from gambling. destination for fun is gone. replaced by greed for profit
Thats what everyone who first time to gamble just for fun then after sometime when they are addicted to it they become greedy to the point that they are losing too much money.
