You're not thinking about this correctly. Both the mass and its radial
distance from the axis of rotation matter here.

And yes, these things make a difference. It's a very tiny difference.
But this and other factors affecting the period of rotation are why the
IERS exists to measure them. It publishes several sets of what it calls
"Geophysical Fluids" data, including water storage and water flux data.
