This makes gamble a game of luck to the poor and a game of strategy to the rich.
Ex:
RICH ($10,000 * 1.10 odds) = $11,000
POOR ($5 * 1000 odds) = $5,000
With this you can see that the chances of the Rich winning is very high up to 90% while the Poor only have 10% chance of winning which now is based on luck!
This makes me think about the saying that goes by "THE RICH IS GETTING RICHER WHILE THE POOR IS GETTING POORER"
The get rich quick mentality is killing the poor.
Even if you have 99% of winning a bet still you can't rule out the remaining 1%. Let me give you a real example why your logic is flawed when it comes to gambling.

Gambling is a place where rich can become broke overnight and also a broke can become rich overnight, that is what the primary reason why gambling is something that doesn't fade away even if we do that for very long time.
