Can you also please explain this model in kid terms?
I don't understand what's going on.

Well, in the image, it would appear that the Earth is warping space-time in manner that assimilates to all known bodies in the universe.
"What is spacetime"
The continuum of existence in this universe that is malleable by the presence of matter. This presence is what warps space-time creating a "gravity-well" which is how gravitational fields are created. Your not going to get a good understanding just by looking at a picture.
"does the picture show gravity in any way?"
Yes. In general relativity you don't think of gravity as a force, you think of it as the geometry of space-time.
