One could be picky and say you’re explaining gravity with gravity. But for the sake of simplicity that’s OK.
I’ve once read an article where someone complained about that and tried to explain it with the actual cause, curvature of space time, like using a model car with glue attached to the wheels. But that was not really intuitive and simple to understand.

I find the metaphor frustrating because of that.

This video includes a much better representation of what gravity is IMO. The creator had the same issue with people describing gravity with gravity.
