Myself have gambled and lost big, once after losing my mind has thought several times I should've at least donated it to someone who is in need. This is most gamblers common mind.
Being bored has made me gamble, but the same hasn't caused addiction I just spend on sports betting. When things went out of my control I started to run to get back the loss which is where I lost everything.
This isn't pure entertainment, we can get entertained when we succeed but continued loss leads to frustration and stress. This way gambling isn't a fun zone or an entertainment platform.
I agree with you on every line you said. People just say it's an expensive entertainment but who the heck actually gets entertained when they lose money? Even a billionaire losing $1 would be sad for the loss. There are people who just want to gamble for money and to cover up they say they are doing for fun without expecting any profit and that's a lie!
I agree with most of your point of view that people play gambling to win money but I disagree that gambling is the best source to earn money. Gambling is a very risky source of earning money because you may lose more than you may win form gambling.
I mostly gamble to get my time passed in a good way but I make sure I do not use more money in gambling.
