I deplore current Israeli policies, but Ukraine isn't disguising its war fighters as civilians like Hamas is, which is an important qualifier to your numbers.
I don't see how that's relevant, nor why such a distinction matters in such an asymmetric conflict where international law clearly allows for violent resistance to occupation.
School children aren’t “disguised Hamas”.
But Russia is doing exactly that systematically for years now, disguising as civilians. I'm also pretty sure Hamas isn't disguising themselves as children, who make up the largest share of the civilian victims.
