This just doesn't reflect reality at all. There are vast drops in the domestic production of things like cars (-85%), motors (-70%), and white-goods (-50%) due to a collapsed import chain. (Russian government source: https://rosstat.gov.ru/storage/mediabank/87_01-06-2022.html) Key economic indicators are flashing red - e.g. non-tax/oil tax revenues are down 20% YoY (Russian Finance Ministry figures from last week). If these are the official Russian government stats, it's likely the real numbers are much worse.

Cars and motors are dual use goods (so the collapse of Russian domestic manufacturing of them is militarily relevant), but even setting those aside and looking purely at single-use military goods, there's persuasive evidence that the Russian military is increasingly reliant on Iranian drones and equipment (https://www.al-monitor.com/originals/2022/10/russias-use-ira...). Vast numbers of Russian equipment have been confirmed destroyed or captured by observers such as Oryx, and those are just the visually confirmed losses you can check the evidence for yourself (https://www.oryxspioenkop.com/2022/02/attack-on-europe-docum...). No country would be able to replace those losses without switching to a full war economy, which Russia has not done (and which would only be a necessary but not sufficient condition for replenishing these kinds of losses).
