Is that true? I mean: is it true that the actions where it was necessary to "order thousands of soldiers to their almost-certain deaths" were significant causes of the final outcome?
WWI was the first 'industrialized' war, trench warfare implied the certain death of a huge number of men if the lines were ever to move, it's basically a never ending meat grinder until one of the parties runs out of warm bodies, supplies or ammo.
The final assault on the remains of the entrenched opposition were without exception extremely bloody and the side that would take the others trench never did so without significant losses.
