These myths can make you lose money or take away the fun. So my advice is: play for fun, enjoy the games responsibly, and when it comes to money, it will come on your lucky days!
Though it's hard these days to see people play with fun considering how people are that desperate of making money the gambling site, you know it's very rare to see people gambles for fun instead gambling to make additional earnings from gambling and is these sets of people that usually lose money and keep chasing after loses.
One thing with gambling is that, when ever there is a moderate gambling you would see the sign of responsible gambling.
