You have just become lucky because you stumbled upon the article and can act on it. So it is not necessary to mention luck, because the readership of the article is already selected for luck.

The article also mentions the necessity of talent.

It also doesn't say everybody can become a billionaire by simply working hard.

Also even if you are born in Africa with no access to schools (or in some US ghetto were everything is sooo horrible), you can probably set yourself apart from your peers.
