I wonder how much money Russia wasted on the Sochi Olympics? It's a big abandoned relic now.
Not to mention huge outlays to subsidies housing and heating bills.
According to Reuters they made $53 million in profits. Other estimates I have seen put the number a little lower at $22 million.
It was likely even more-importantly a propaganda coup for the Russians in the sense that they were widely criticized by many far-left led nations for being "anti-gay" (non-inclusive) and of course because of rising tensions in Ukraine (about which I have mixed feelings, but largely side with the Ukrainians). The actual invasion/annexing of Crimea by Putin did not take place until some time after the Olympics had concluded.
It was also a demonstration of Russia's ability to provide a secure space for international events even under the constant threat of terrorism from the muzz.
Although much of what you posted is true, comparatively Russian external debt is among the lowest of any major player in the global economy (about 25% of GDP). That is mitigated by other extraneous factors and does not diminish the truth of Geronl's central point that the Russian economy is far from trouble-free.
They are still struggling, as the Chinese, to move into the 21st century as not only a military super-power (as both unquestionably are) but also to become qualified economic superpowers ( China is closer to that than Russia at this point).
