That is nonsense.

Widen your thinking a little bit more!! I will help you with that by a simple question: can Spain produce what Russia can?
The answer is NO, Spain’s GDP is mostly about services, Russia GDP is not.
Russia is one of the few countries (and I mean really few), who can produce domestically everything from a screwdriver to space rockets, tanks, jet fighters, airplanes, fridges, TVs, cars, and the only country to have a fleet of icebreakers that can navigate through the north pole as if it were a highway. Spain, on the other hand, cannot produce everything that Russia can, even though they have a similar GDP. That’s because GDP or GDP PPP are measured by quantity of goods produced by country.
So, for example, let’s say Spain produces only olives (50 tons) and they sell them for 1 $ billion, Russia is producing 10 tons of olives and 1 tank, 1 space rocket, one TV and selling them for 1$ billion. The GDP here is the same, it’s 1$ billion dollars. But of course you can clearly see who is stronger here, simply because Russia can during an emergency or a war or in case of a demand raise the production much much easier than Spain can diversify its production from olives to tanks
