No it's not, the budget deficit information comes from Russia itself.
And even these figures are artificially pumped by factors like the previously mentioned "trade in local currencies". India pays for oil in rupees, which are piling up in Indian banks because there is no use for them. Russia has no comparable demand for Indian goods, can't exhange rupees for other currencies, can't pay to third countries in rupees, and is unwilling to invest that money in India. Oil flows to India, nothing comes back.
If this is how Russia "successfully skirts western sanctions", then may it continue for a long time.
The Russians have a deficit of over 40 billion dollars, it doesn't look super rosy.
Additionally they are losing a lot of people in the war and having countries cancel military equipment orders.
