That sounds like a lot of shyt. Not sure how much they spend on the military but it might take them awhile to replenish. They can't possibly be ready to touch another war anytime soon.
Russia inherited its massive stocks from the Soviet Union. However, a good part is not in good condition or well maintained obviously.
But on tanks alone (they supposedly have between 12k and 20k), they lost more than the entirety of France, UK, Germany and Polish stocks combined and it's said that it's only equal to 50% of its usable stock. What's left is likely old or low tier stuff though.
Considering how hawkish Putin and potential successors are, I wouldn't be so sure they won't go to war after (if they ever finish in Ukraine). There's not many things that they did in the past months that could be explained rationally at least from a Westerner POV.
