Winning an Olympic gold medal is similarly difficult but I'm sure you wouldn't say that it's just a lottery and not worth writing about.
Even putting aside the degree to which a gold medal relies on recognition of both measuresble inborn talent and acquired expertise, it’s not very similar. We’re not talking about success being difficult to achieve, so much as a certain scale and type of success being impossible to predict, possessing exceedingly low odds, and being largely random within the pool of “people trying.” If we”re being honest that describes lotteries and this story, and not Olympic gold.
If you think it's pure luck, then that means building (this) business is no different than winning the lottery - which you specifically said wasn't the comparison before.
If it's not all luck, then that means success takes difficult work and odds only further show the challenge in getting to this scale, in which case it's perfectly fine to write about.
So which is it?
"a certain scale and type of success being impossible to predict, possessing exceedingly low odds, and being largely random within the pool of “people trying.”"
Ok...? This isn't relevant, it just shows thats its difficult to get there (with some luck required).
