You're blindly relying on information from a combatant aligned side in the midst of a war which has had an unprecedented degree of 'information warfare' with the claims of one day constantly shown to be lies of tomorrow. You should ignore most of everything except that which is completely falsifiable. Deaths are 'kind of' that. They generally are not going to be made up, but figures are going to be massaged. Civilian deaths they will be overestimated, troop deaths they will be underestimated.

Videos can be fabricated, misattributed, misleading, or all of the above. But the data is in the deaths. You don't have a substantial intentional targeting of civilians and only 200 civilian deaths over a period of years. It's just completely nonsense. That's an aspirational rate of minimal civilian deaths by the standards of most of any conflict.
