Again, you are confusing causalities (wounded and dead) with KIA (just the dead). That's why you are getting such different numbers. Its a pretty easy mistake to make and there are lots of media reports that make the same mistakes.
PS Also, some numbers count civilians and others just count military. And usually civilian dead > military dead in most wars.
That last point (fortunately) does not apply to this conflict. In fact, the fraction of civilian deaths might be the lowest for any conflict with comparable casualties. I haven’t verified this, but would be interested if someone did.
