They have similarities such as you mentioned but only at relatively low energies.
There are several sorts of plasmas. An ionized gas is a sort of plasma, also called thin plasma.
Thin plasmas, while physically different from a metal, share a surprisingly large number of properties with it:
They both have two separate charge carriers, cations and electrons.
On both, the cations have a negligible contribution to current and the electrons form a gas.
They have similar dispersion relations (leading to similar "local" Ohm's law in both).
It's because cations don't contribute much that they seem similar, in spite of one being a gas and the other a solid.
