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?

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.
