And specifically *only* the story gacha. Outside of specific event gachas, you can't get them from rolling in other gachas, unlike someone like EMIYA who you might get at any time. Thus, they're quite a bit more difficult to get randomly unless you invest quartz into trying the story gacha, which can give you any servant outside limited ones, thus you need quite a bit of luck to pull a story-locked servant from there.
