Based on that argument the image captured by my 20mp phone needs enlarging the same as my m43 20mp image if I am viewing the results at the same size, which is not correct.

The size of the image captured will determine how much enlargement is required to view the image at a given output size.

What does it mean in practice?

Hypothetically, if I shoot a scene with m43 at f/2.8, 1/100, and FF at f/5.6, 1/100, both 20MP, what kind of theoretical difference should I expect, assuming the necessary enlargement is the only factor?
