g is not gravity, it’s a constant that quantifies the force that gravity impresses on a mass in Newtonian mechanics

https://en.wikipedia.org/wiki/Gravitational_acceleration Isn't "G" (uppercase G) is gravitational constant and Lower case "g" is acceleration?

[nsonha]

yes but they have nothing to do with your assessment "gravity is acceleration". "Forces cause acceleration" is more accurate, there are 4 kinds of forces so gravity is just one cause.
