They prevent too much excitement as they always have that good control with both their time and finances.
There is no doubt about that, in fact there are players who have so much discipline that not even emotions are something that motivates them when it comes to playing, they only have the game to enjoy it in a healthy way , reaching that level is something great, but obviously to get there you need to go through many things, experiences that make us wiser and obviously will keep us away from addictions.
Yes you are right if we become addicted then maybe it will be very bad for us. Because if a person gets addicted to something then that person will do that thing every day. Whether it is bad or good for him if he gets addicted then he will do it every day. If you are not addicted to gambling but if you take it as a fun then it will be good for you. Because you will not be so addicted to gambling you will gain a lot of experience over time. You will not spend so much money before education. If you get addicted to gambling then you will gamble every day and if you lose then you will gamble more aggressively and then there will be a lot of pressure on your head and you will keep making one wrong decision after another
