The pressure on Russia's manpower is not the plain old number of humans in the country, it's the amount that they can commit to this war without having so much of a domestic impact that public opinion turns against the government too much. Ukraine has a quarter of the population but has the domestic support to be able to call up everyone that can fight. Russia doesn't want to do this, so it uses the likes of Wagner and prison conscripts that won't be missed by much of the general populace.
