They might not do any, it might take 10 years, they might repair them but not modernize them...
If we just take this at face value though, it doesn't make any sense. Russia allegedly has 8000 T-72s and 3000 T-80s in "Active reserve". Even at the highest possible estimate of casualties, they should still have thousands of those left. Even if those tanks are completely unfit for service, it should be easier to return those to service then 1960s tanks in even worse condition. T-62s require more people to operate (4 instead of 3), have no parts supply chain, and have a much weaker gun, which might be extremely relevant if the US starts handing Abrams to Ukraine, which seems increasingly likely. They are just worse tanks that cost more and take more people. And they should have more T-72s then T-62s anyway.
... except they clearly don't have those T-72s. What happened to them isn't clear, but Russia has already been slowly feeding in T-62s, and it seems most of the tanks available to new units are those. There are plenty of theories of what happened to them, but the most likely theory is that Russia never made as many as it claimed, due to factory miscounts. Still, they at least still have some. One theory is that Russia is nearly completely out of the 125mm ammo that is shared by the T-72, T-80 and T-90 tanks. Expenditures have been high, but the real kicker was the number of ammo dumps they lost to Ukrainian Artillery. They still would have stockpiles of 115mm ammo, so despite the fact it is worse, they actually have it, so they need a tank that will shoot it.
