The real reason why we have gravity is not only because of space
curvature, but also because of time dilation,

Utter nonsense.

the two basic tenets of Relativity.

“Time dilation” is just the kindergarten explanation for less elapsed proper
time. Obviously the actual concept of spaceTIME curvature INCLUDES this.

Space curvature is easy to visualize, but not so much time dilation.

See above.

Here they visualize time dilation like fluid flow.

“They” are LITERALLY giving a kindergarten explanation there by saying that
“gravity is curvature of spacetime”. NO, IT IS NOT: It is ONE observable
EFFECT of the curvature of spacetime.
