System Cache Not Cleared

The storage space on my computer continues to decrease steadily after clearing application, system and browser cache. There is 1.35TB of system data which most of it is cache. I don't have this issue with other mac devices. Can you review if there is an issue clearing system cache with the following specs?

MacOS Ventura 13.5

IMac 27", 2019

CCleaner Mac Version 2.8.173

See attached system storage.
