(1) gambling is a form of entertainment, not a way to make money/profits.
From the words
gambling = entertainment, we can already say that gambling should not be taken seriously.
Likewise, don't take capital for gambling seriously, don't use a lot of money.
If you use a lot of money and gamble seriously, it will eventually become a problem for the gambler's life.
There is a lot of gambling in the area where I live which ends in misery and has social, economic and family problems. This is very sad because they are so sad for me to look at.
