This is typical case of https://en.wikipedia.org/wiki/Pareto_distribution#Occurrence_and_applications https://en.wikipedia.org/wiki/Pareto_distribution#Occurrence... - Very few people got lot of money; much smaller number got moderate amount and have profit; all others are unprofitable. But this is about natural things. - In most countries, distribution is distorted by taxes, by regulations and by technical progress. What I read from statistics, 100 years ago, in US most people where poor, but exists very few extremely wealthy humans; after science-tech revolution and two wars in 1940s, in US appear large middle class. And (this is from talks) latest 10s years, middle class divide again, so there are more people with more than million, but also more people from middle class switched to poor. Probably, the same happen with small game dev entrepreneurs - 10 years ago, I myself have seen significant number of successful people, but after that, I see, some people remain successful, but others become ordinary.
