Its not wrong. Its just a matter of doing it and self-control. You need to consider also your losses. If it continues then maybe its time to slow down. Make sure to manage your losses and find strategies to win more. Experience is a key and assessment in every game you bet.
Anyone who can have self control and probably gamble for fun or some of the good reasons without being too attached to making huge profit or getting plenty money from luck without working for it which is what usually make some people get addicted to it anyway, then is not wrong. When you know gambling is affecting your life and the lives of people around you, then you should know that YOU are wrong and not gambling.
We dont need to be attached to gamble, we play and leave. That is all we need to know, we dont need to come back because we feel that we need to get back what we lose but we come back as a new term. It is not wrong to gamble but it is wrong trying to get back and try to win the money that we lose from gambling
