For example, a good gambler knows that although the lottery has a $100m grand prize, there is a much less than 100M/1 chance of him winning by buying a dollar lottery ticket. Whereas a good gambler would rather bet on the $1m grand prize lottery that has a 1.5M/1, as statistically, his equity is higher.
As for being warped by media, most new gamblers are warped as to the frequency of winning based on what they see on TV when reality this neglects the millions of people that didn't win.
In my Risk and Finance Manager career, I worked for multiple Betsoft, Netent and RTG Casinos, including the big brands. I know this Business. I came here to say that I like the OP's Post a lot, this is how it should be. And this Thread got even better, this addition here from Spiker is truly amazing.
I personally don't gamble but I pay couple EUROS for playing MMORPG's, I can't even win Money. With gambling, you could... IMHO gambling is another Form of Entertainment, not more and not less. Like going to see a good Movie, play a Computer game or another Hobby perhaps. Just always need to keep in mind that Money is involved and follow the OP and spiker777 input here, really nothing to add to it, its perfect advice.
cheers
