Thing is, soviets claimed a kill when an enemy tank was damaged, and they also claimed a loss when their own tank was damaged.
But really, who cares about what allies claimed to kill?
It's important to look at the actual statistics made by the accounting of both millitaries, not kill claims. When it comes to kill claims, germans used their own method of counting losses and claimed to kill a tank even tho it was later repaired.
You need to look at the statistics that are determined by the documents, and then make need to make them equal to one another since the method of accounting for losses are different, and then you can actually compare them.

German documents say only 25584 tank losses on the eastern front. Historians set the soviet tank looses to around 83500. No matter how you Count the soviet losses the german tank losses are still much less than the lost soviet tanks.
