The difference isn't technically with consumer vs enterprise, but with how big in scope something is.
For example, it's likely that something as big and successful as facebook is due to a once-in-a-lifetime opportunity and idea, but a neighborhood pizza shop can be more likely to be successful due to experience, skill, and non-luck factors.
Consumer startups just happen to usually need to be big in scope in order to succeed.
So outliers like Facebook, apple, etc may actually depend on luck to become as big as they are, but smaller scope enterprises may be more formulaic and repeatable.
