Gravity is everywhere. There is never any actual true "zero gravity" in the universe.

But if you're in freefall - meaning following gravity's pull rather than resisting it, or being blocked from following it (by the floor, your nearby planet, spaceship walls as it thrusts, or whatever) - you don't feel it, and that's the thing we call "weightlessness" or (wrongly) "zero gravity".

The weightlessness you feel in a spaceship far from any object, is exactly the same weightlessness you feel on board the ISS orbiting earth. There aren't 2 kinds ("artificial" vs "real"). You can see that because if you zoom out your focus a bit, the spaceship "far from any object" is in fact still falling towards some object, perhaps at very high speed. Its nearest galactic cluster, or supercluster, a few dozen megaparsecs away, perhaps,but its still falling fast towards it. If it doesnt hit anything, it will follow a path that forms a (probably highly) elliptical orbit over hundreds of millions of years, since it wont lose energy and collide. And the ISS is still following earths gravitational pull, it's also going to remain in an elliptical orbit too, if you ignore energy loss from the trace atmosphere at that altitude. Identical behaviour, just on different scales.

So there isn't any such thing as "artificial zero gravity", or a distinction between some kind of zero G thats "real" vs. "artificial", apart from simulations like floating in a water tank or other simulators.

If you are freely moving as gravity dictates, you will experience the sensation we call "weightlessness" or "zero gravity". If something stops you doing so, you won't (or will feel it much less). Its that simple. *

* For completeness, if something only slightly stops you from freely following gravity, or the local gravitational field is weak anyway but some object you're pressing against stops you from following it (eg on the moon), you'll feel this as low gravity or microgravity.
