There's a chance the story events for the card dont all appear in one career, in which case you dont get the opportunity to get the skill hint. You know there's 3 story events per SSR card, and you get the skill hint on the last one. But it's random which events you'll get in any career, so yeah you might use Super Creek card but then you might not get all 3 of her story events so no Swinging Maestro.
And for some cards like Special Week SSR the skill hint in the 3rd story event is random too, so even if you get all 3 story events in 1 career she might only give you Hydrate instead of Gourmand. That's why Special Week doesnt give Gourmand as often, there's 2 rolls and you have to land both to get it
