I don't get why people think Russia will operate a carrier when Germany does not operate a carrier. Russia has no need for carrier considering Russia has no far away island.
Russia has been acquiring naval bases abroad. They seem to want to project power to the Mediterranean and the Middle East.
I agree that carriers aren't necessary for a country like Russia but their government seems to think otherwise.
Even if it is not their top naval priority.
Germany is a bit of an oddball because their coastline is tiny and their defense posture since WW2 has been one where they don't use their forces abroad except in exceptional circumstances.
Their GDP PPP might be higher than the most but that's just an indicator among many others, means little on its own. Though for Russia, money isn't the only problem as their industrial base is generally weak. They can't seem to develop their existing naval yards and facilities no matter how long they plan. Just look at their naval modernization projects and see the mess they have to deal with. When it comes to shipbuilding, you can regularly read about funding problems.
Here is an annual piece on CGN Admiral Nakhimov's progress (Project 11442):
Progress has been painfully slow but the shipyards have improved and they increased self reliance on components like naval gas turbines and marine propulsion in general. Russia is presently building a Project 10510 icebreaker for example. It is to have close to 70 000 tons displacement, a length of 209m, beam of 47.7m, with two nuclear reactors of 315MWt power each. That basically puts it in the same size and motive power as a carrier. It is being built at Zvezda shipyard in facilities which only became operational a couple of years ago.
Prior to that Russia didn't have facilities to build ships of that size. The large shipyards in the Soviet Union were in Ukraine.
Russia, unlike what some people say, prefers to focus on the economy before their military. For example had they built cruisers instead of icebreakers they would have launched three of them by now. So things like icebreakers get higher priority than military ships.
