It's "tough" only if the listener is too dense and incapable of understanding that the (true) statement "The Ukrainians have destroyed lots of Russian armor" and/or "The Russians have lost massive amounts of armor" is NOT equivalent to the (false) assertion "The Russians thus have absolutely no more armor left that they could lose."
The Ukrainians have inflicted devastating losses upon the Russians. Further, Russian cowardice / unwillingness to fight, the sheer incompetence of Russian leadership, and the catastrophic state of Russian equipment and/or abysmal Russian supply logistics have been responsible for further massive losses.
This does not preclude the possibility of there still being large amounts of Russian matériel still waiting to be destroyed by Ukrainian forces or abandoned by retreating Russian troops.
Regards,
To the extent Russia still has significant armor remaining, it is overwhelming going to be already dispersed in the field to operating battalions and brigades, not sitting in a park to be captured.
