This assumes that you have the option of not gambling. However, you are forced to use the roulette table by fiat currencies. How much will USD be worth in 5 years? Who knows. It's less risky than other options, but a sure loser in net worth with inflation. The only way to not lose is to adopt some type of more risky position (AKA gambling).
