Betting is all about luck, because the chance of winning is only a few percent of the total money you bet.
That's not true, you could place bets with 99% chance of winning. More important factor to consider is the house edge.
How can a gambler bet with a 99% chance of winning?
As long as I play gambling, I have never come across this opportunity. If anything, it's only very low Odds but comes with a great deal of risk because to make a decent profit requires large amounts of money to be wagered.
Talking about the house edge, there is no such thing as a house edge that lets gamblers win easily.
