YouTube view count is not accurate. Some own YouTube has its own unethical way of determining if a count is genuine or not, to be politically correct their site says that YouTube determines the quality of the view.
Some of the reasons are that YouTube algorithms determine if a video is consumed only in a certain network like a family video or does it have the scope to be shared. There are many such illogical algorithms that make it unfair especially to smaller YouTube channels. Sometimes the algorithms also catch fake views and subscribers.
