I have seen those estimates as well. These sites usually document confirmed losses, that is, with certain documentary evidence of them being destroyed. There is however a very large number of undocumented kills and what is more interesting, documented kills that are not actually kills..

However, despite the questionable numbers, it is clear that RF cannot replenish the tanks as they are being lost. They are using up their stores or stored tanks, which many times can only be repaired using 3 vehicles to get one fully working, many times without some of the systems and many many times wihtout the most advanced sights, comms and other tech-intensive features.
