Okay so to expand on this:

First of all I want to say that this is all naturally my own perspective and that you don't have to agree with me, it's just one of many ways that I use to categorize fictional works because I find it incredibly fun to do so. https://twitter.com/UchihaShadow123/status/1274478992712744961

Also naturally no work is gonna be 100% only one way or the other, I think they simply lean more towards it.

So I guess I should begin by explaining how I define "story", from my perspective, the story is the combination of all the plotlines, character arcs and the themes they convey, it doesn't include things like world building, atmosphere, and characters on their own(only their arcs)

Regardless of if that story is plot driven(external conflicts are more important) or character driven(internal conflicts are more important)
Works that function more as a story are works where most elements(characters, concepts and plot points) within it exist to serve that story

In a way, you can say that those elements only have value when viewed in the context of the story, and they lose their value outside of it. It's like an orchestra, all the instruments work together in harmony to play a piece, but each instrument doesn't hold much meaning alone.

Usually in those works, there is a big and clear conflict throughout the whole thing from beginning to end, it might get expanded on, recontexualized and become more complicated, but ultimately everything will revolve around that conflict-

-and once that conflict is resolved, the work will essentially be over in the truest sense, there is no room for adding more to it.

Now works that function as worlds/universes are different, they are more concerned with establishing a setting, and developing character ideas and concepts regardless of whether or not they contribute to the story, and they tend to be pretty disconnected from each other.

These works also tend to have various different conflicts, with no central one, even if the current conflict is resolved, the state of the work at the end of it leaves room for more conflicts, regardless of whether they are canon or fan-made.

You can almost describe these works as a stream of ideas, they might be disconnected, they might be chaotic, and they certainly don't play as beautiful of a song as the orchestra does, but they are always refreshing and have the highest creativity in comparison.

I think the authors who create those works are not constrained with telling a great story, instead they simply want to create a world where they can insert all of their ideas into, regardless of how well they mix up.

Finally I want to say that I don't think either of those methods are better than the others, and all the examples I've used in the original tweet are high favorites of mine, but whenever I feel creative desire, I find that I'm more of a universe creator than a story teller

Which is probably why I feel so attracted to series like HxH, Fate/Nasuverse and ASOIAF despite them not having anything that resonates with me on a personal level, instead it's because I feel like I can relate to the author's way of writing which inspires me.
