USSR won because of American lend lease and Germany having to fight on two fronts. Modern wars are won with equipment and technology, not human wave attacks (see Russia Ukraine war)
Lend lease wasn’t a major contributor to the eastern front, however the North African campaign was.
It pushed German logistics off the edge, forcing them to allocate most of their heavy lift aircraft and fuel to try to keep North Africa.
That said Ukraine isn’t binary case either. Russian problems in Ukraine seem to go well beyond just logistics and are plagued by lack of strategy and even a remotely competent military leadership.
The technological advantage Ukraine has isn’t what led them to prevail.
If Russia could employ even basic combined arms warfare and conduct organized advances that serve a singular strategic objective the result would likely be very different.
The question is right now is where the people element of the Chinese military sits.
