I think luck here is referring, mainly, to risk taking - a giant corporation is not going to be the company on something that has a 0.5 probability of happening, but a startup might.
For instance: All these startups around self-driving vehicles. There's a non-zero chance the publics current unsettledness swings to full on majority disapproval, leading to gov't regulation killing self driving cars.
You can set yourself up to maximize the chance of that not happening, but but you cannot bring the probability to zero. Hence, these startups all rely on being "lucky".
Meaning, unlike what I felt you are implying in your comment here, startups are often and in many variables betting on probabilities that they are not in control of, aka luck in the exact same sense as a lottery ticket.
