As i said the key thing isn't how many, it is who, how and what for.
Israel started the war in response to the genocide of Oct 7. So all the legitimate collateral victims and damage from Israel's actions here is responsibility of the perpetrators of Oct 7.
You aren't calling for prosecution of the perpetrators of Oct 7. That is already shows your colors.
Anyway, the number of killed you cite comes directly from Hamas (its Ministry of Health stated those numbers to UN). Hamas is a terrorist org, and can't be trusted at all.
There is no evidence that Israel killed civilians in any meaningful numbers, and that the killings were criminal and not legitimate collateral.
Now, there is a million of cell phones in Gaza. After several years of watching Ukraine war anybody knows the amount of cell footage to expect. Some Russian killings in Bucha were recorded by reconnaissance drone for example. Russian soldiers posted videos of them executing POWs, security cameras recorded Russian soldiers marauding and so forth. Where is pretty much no footage comes from Gaza. "Israel soldiers shoot at the crowd at food distribution center" and nobody recorded anything (especially giving that according to Hamas it happens regularly - and still no footage!)
And on rare occasions when some footage comes out - the analysis in the example below shows that the basic laws of physics wouldn't let even 20 people to be killed when Hamas claimed 400-800 in that "bombing of hospital" (again, if you watch war footage, you'd know what gore of several people killed by explosion would look like, and no way the parking lot would look that way just the morning several hours later - where is all the blood for example? it is pretty obvious that the asphalt hadn't been washed by the time photo was made so blood should be there even if they picked up all the bodies and parts of it)
