In options trading, every dollar you earn is a dollar someone else lost while trading options, and had to give to you. It's zero-sum. If you include fees, people lose slightly more money than they gain in options trading, on average.
This is pretty different from YCombinator's startup investment. No one has to lose for YC to win. The money ultimately comes from customers of YC-funded startups, who are in theory engaging in positive-sum trade (getting more in value than the money they paid for it). On average, people are earning lots of money investing in startups.
To be clear, options trading does have value in terms of letting people buy insurance and providing a price signal in terms of how many people believe prices will go up or down, but this is comparatively marginal and doesn't affect the options traders themselves.
