It's important to note that Nazi Germany mobilized something like 18 million people over the course of the war and saw over 5 million military deaths. When Stalin suggested that the Allies would need to execute 50,000 Nazis after the war, he was talking about a small sliver of Nazi leadership and those most directly culpable for atrocities.
Just discovered that only 13 Nazis were actually executed, along with 20 life sentences. There were also 100 or so who ended up serving 5-10 years. Always thought it was much higher, seems like the execution number should have been at least 1000.
