Exactly! The person you replied to did the right calculation but completely threw away the context. The argument here is akin to p-hacking where all the investors in the world are the experiments and this article merely picked the one that got lucky.

Different scenario but similar argument, I roll a large set of dice, 5x rolls each die. If the set is large enough, one of the dice is likely to land all 6s. While that is unlikely, that doesn’t automatically mean the diced are unfair. It’s not just enough to reject the null hypothesis but you also need to prove the new hypothesis. Not to mention having a solid working theorem for why the alternate hypothesis is correct.
