In gambling its all about the risk you will make a high rolls to make a high return or a small pne depends on your capability to have risk management considering the type of game at the same time because people would like to risk with a slot games base on the luck or else with the table top games and sports betting base on the skillls, knowledge and analytics. So its all up to the players how they handle the risk of gambling.
So...
My opinion the high risk doesn't always mean simply betting a lot of money, but rather taking in greater exposure to uncertain outcomes... and for achieve this there are two ways to deal with risk:
1. Pure risk with blind bets;
2. Calculated risk with strategic management.
In the first, you simply increase your bets or place them based solely on luck. This are complete nonsense, because the chance of a "high return" depends solely on chance.
That's why I prefer sports betting, because then I apply the second point that I mentioned... I analyze the probabilties, statistics and truly understand the advantage. This way, I can reduce the impact of losses and increase the consistency of winnings, even with high risk.
Don't be like most people who confuse taking risks with reckless betting... you have to take risks, but you can do it intelligently, and that's what makes the difference in the long run.
