You've got to give luck an opportunity to find you, by getting involved in things.
Once the author saw the opportunity, he then pivoted to exploit it through a lot of time and effort. It's pretty clear that other bot makers did not see that opportunity, or saw it and did little.
My perspective is you make your own luck - and really you are making a lottery ticket with probably much better odds than a real lottery ticket, and other upsides (if you fail you gain experience). But it's still a lottery ticket so it is not always useful to disect someone else success and say "oh they woke up at 4am every day, so I'll do that to be successful" etc.
