Personally, it's very easy to gamble responsibly. I've been gambling for close to a decade now, and I've learned to gamble responsibly, but if I'm to answer that question generally and not personally, then no, it's not easy.
It's not easy because the casinos and betting companies plant the ideas in the heads of customers and potential customers that they can get rich from playing. With an idea like that, people won't think about how much they will lose as long as they get out of poverty. Add that to the stories they hear of people who won hundreds of thousands of dollars in betting, and it changed their lives. Stories like that motivate them to think that one day it will be them
Then there is the chasing of losses. You want to get your money back, and there is a voice always at the back of your head telling you that the next bet might be the one you'll win big and recoup all your losses. So, we can see its very difficult to gamble responsibly, but it's very possible.
The question about if it is easy to be a responsible player? Merely looking at it one will know that such question is on the general perspective because while it might be easy for you it might not be easy for the nearest man, and provided that one has not quite gambling it is still an everyday struggling because change is what is constant, where a long term responsible gambler can turn to an irresponsible gambler, it is not easy and I must say but it is so important to keep being stronger than ever not to fall a victim of such circumstance because it is not actually a good thing. We talk about it here everyday and the negative impacts of it to a victim.
