There is nothing wrong with going to college, but you shouldn't be going because you are following someone else's plan, you need to be there because you know it is the right thing to do for yourself. Bottom line: Don't worry about what other people are doing.
Evan Williams, Jack Dorsey and Biz Stone are other examples of college dropouts who left not to start startups and then became successful entrepreneurs. Matt Cohler left college for two years, working for a startup in China and playing in a band, before finishing up his college degree.
Each individual has to choose the path that is right for them. Every incredibly successful person is an outlier. You can learn from them but you can't just copy them

This is true. But the whole premise of YC and other startup incubators is that there are things you can do to significantly increase your odds of being successful if what you want to do is to found a startup.
Your chance of becoming Larry Page, Bill Gates, or Mark Zuckerberg is incredibly small. But your chance of founding a startup with some degree of success will be better.
