Obviously. Your point? There is no "c" on the left hand side
of the equation E = m c^2.

Actually, E = gamma m c^2, or E^2 = p^2 c^2 + m^2 c^4.

I see only that you do not understand what setting c to 1
means.

The dimensions do agree when one chooses the units accordingly.

Err, "dimensions" (in the sense above) is a concept of physics,
not of math.
