> 90% of the german military were destroyed by the Soviets in the eastern front
This is probably true of the Germany army, but not the air force, and certainly not the navy.
Furthermore, it does not demonstrate your point that "Bletchley Park ... had no material impact on the war", which is demonstrably false. See for example https://en.wikipedia.org/wiki/Ultra for a list of some contributions; but it is surely obvious that reading the enemy's communications is going to be of great help in a war.
> Germany had no chance of winning.
True once they were fighting UK + USSR + USA; the odds against them were too great.
