Anon finds a plot hole

Felix Felicis is a potion sometimes called “Liquid Luck.” Until the effects wear off, all the drinker’s endeavours will tend to succeed

Harry Potter has an in-universe luck potion. Based on that wiki page, it looks like it was only relevant in the sixth book/movie

Dumbledore gives Harry some potion that basically increases his luck stat by infinity. I forgot what they actually called it.
