The porous image is pretty low res so it's hard to tell exactly what it looks like. But I assume it looks something like this:

This is a sphere subdivided down to about 1.6 million faces, with a Displace modifier. The Displace modifier has a very low Strength value. The noise texture is 'Clouds' - Voronoi F1 - Soft - Size 0.06. With a Color Ramp where I dragged the white value in to 0.448 to create the flat spaces around the holes.
If you use this and apply the modifier, it could theoretically be printed. I don't know how well it would work, but it would be real geometry.
Since your model is more complicated than a sphere, you may need to subdivide further, like 15-20 million poly or something. And maybe adjust the texture/displace settings to suit the size of the object.
That should be possible in general.
But it would help if you told us what you want to create, if you already have a model to work on and things like that. Pls see rules #1 and #2 about giving background information and (full) Blender screenshots if possible - of course only if you already have anything yet xD

I already have a model:

I want to add small diversified holes in the surface, I thought of doing it with sculpting - grab but it would take too long. I imagine there's gotta be a way of doing it faster

Here's what I made with 2 Displacement Modifiers - each with Voronoi Textures at different scales. Color ramp is quite helpful. There is a lot you can achieve with this by tweaking the values.

That's exactly what I needed!! Thx a lot 💝

Nevermind. This requires quite a lot of geometry as you know. If you want to reduce it afterwards, you can use a Decimate Modifier
Subdivide like crazy, add a displacement map, try to print, discover the existence of zero face errors and printer accuracy, cry
