You do realize that you can play hundreds of poker hands in a night. For your analogy to hold, you'd need to be able to start companies for a million years.
Of course! There are professional poker players who run bad for months at a time even. Variance is a cruel mistress. That doesn't negate the fact that talent certainly gives you an edge in poker or in the startup world. It's easy to say it's all luck, but that attitude doesn't pay service to the many successful people who had raw talent or an excellent idea in addition to the luck that allowed them to become successful.
