You've got a link from Anne, but I'll at least describe generally what the different motion controls are, because they can be a little confusing at first and how they relate to one-another...
When it comes to adjusting the motion properties of Essential Graphics text or graphics, you have three options.

1. Vector Motion - Vector control over all the various graphics layers. So no matter what you have going on you can reposition them all at once. This behaves just like the regular Motion properties of the clip, but it's vector, so it's lossless and without borders.
2. Individual Graphics/Text Properties - This is what it sounds like. If you twirl this option down you have most of the same controls that you have inside of the Essential Graphics Edit pane, including a section for Transform, where you can adjust vector properties for that individual text/graphics element. If you are adjusting the properties inside of the Essential Graphics Edit pane, you'll notice that they are tied to these properties - they are connected.
3. Clip Motion - This is the same clip motion control you have on all your regular video media. As a general rule you do not want to use these to adjust your Text/Graphics elements. It's not vector so you'd notice lossy behavior when scaling (up, in particular), and since you are moving the clip around that all the graphics are "riding around on," you can accidentally move your text/graphics elements off the borders of the clip, as shown in this gif:

So, generally speaking you want to avoid the Clip Motion (3) properties and instead use the Vector Motion (1), which will do the same thing but with vector and borderless behavior. Obviously once you know what each property is doing you can break this rule and use the regular Motion. There are situations where maybe you'd need to do that.
Hopefully this helps to clear up some of it!
