It's actually good to bet on higher odds but the possibilities of winning are extremely poor because they are higher volatility games. When gambling it's better to only bet on low odds, this could make it that possible to win although we know that chances and probability determines it, when a gambler goes for a lower odds or even bet on single games it creates that chances of winning to be at least 40-50 percent. Another most important thing should be gambling with an amount that is riskable than gambling on a higher volatile game with a higher amount with the intention to win and still lose them.
