Iran is the 17th most populous nation in the world, with 93 million people. These protests seem to be occurring across the entire nation. Another comment mentioned over 4,000 separate clashes. Other sources have already corroborated a lower bound in the mid-thousands. I think the burden is on you to refute these numbers by showing that the sources are deliberately misleading or finding a flaw in the methodology. Simply saying that you find them "not credible" and that some people might have a political motive behind sharing them is not an argument.

Note, I'm not saying that they have been confirmed, but I do not think that you have given sufficient cause for rejecting them out of hand.

This is the organisation most commonly cited in news reports, they estimate ~5200 protestors confirmed killed (+ a few hundred more for security personnel killed)

They are a group of anti-regime Iranian dissidents based in the US. I don't know why they would seek to provide a deliberately low estimate.
