i've been purchasing some textures of Textures.com. The thing is that some of these have a displacement and some others have something called "Height". At first i thought it was the same thing but after watching closely, they don't seem to be the same (or maybe i'm bad at observation).

The thing is that i need to know what does this map mean. It's the same as a "displacement" map?

If not, where should i connect it in the node editor?

EDIT:

You can see the differences here: https://www.textures.com/download/substance0043/127911?q=seamless&filter=3d_materials

The thing is that in a displacement map, a valour means sinking and the other lifting, but in the second texture group you can see that a black valour(which is sinking), is in a place where in the colour image is not sinking but lifting instead (a lifting flagstone).

You can see the same happening here in this texture pack: https://www.textures.com/download/substance0045/127923?q=seamless&filter=3d_materials

While in this other, instead, the height map looks more like a displacement map: https://www.textures.com/download/3dscans0027/126894?q=seamless&filter=3d_materials

Now you see what i mean?

The thing is that these texture (mostly or entirely, i guess), are made for Zbrush

I hope this clear the things up :)
