I’m sure I’m not really understanding gravity theory, but I have in mind the illustration of marbles on a bedsheet. If that bedsheet is space-time, why isn’t there some sort of universal up and down as objects relate to each other?

Unfortunately, as a human you won’t be able to visualize the reality of the warping of space-time due to gravity/energy. The only reason we can apply the concept of this kind of warping to tell us useful things is because of Einstein and the metric tensors in general relativity.
To paraphrase Mandalorians, “the tensors are the way” (via the related math) we can calculate and deduce new facts about the universe (if the question is related to GR).
But the main issue is not just that we exist within the 3 dimensions that you want to visualize, we have an issue visualizing how time warps as well. We exist in a reality where time has one dimension (forwards/backwards). But when space-time is warped, that’s no longer true and we don’t have a good way to intuitively visualize that outside of just noticing that time ticks slower in the presence of large gravitational fields. But that ticking rate is a consequence of space-time curving and we can calculate it all with those tensors.
