Lol, betting is better off to ponzi, in ponzi you don't work at all for the money, one just sit down at his parlour seeing his money grow just like that. That's why, it is a scam type of investment. But gambling takes hardwork for one to win, predicting actual result is not a yardstick, people must lose gambling. The ones that lost their gambling, will multiply more money for the bookmakers to pay those little that won and the rest money goes direct to the bookmakers account.
This is true. Betting is more like gambling and what you win is based on how good you can be able to predict outcome of games. This is not the same with ponzi schemes where investors are promised that once they invest, they don't have to do anything and money will start coming.
