I don't think we'll know exactly until after the war ends (and hopefully the russians are pushed back to the '91 borders). There is a huge disparity indeed, but not all of them are concentrated in the areas of conflict right now (I bet a large chunk of them are still in western Ukraine) and the russians were indeed able to target and destroy a couple of weapons transports, so who knows how many of them never even made it to the Ukrainian armed forces.
