Freed memory instantly used up by "System" and "Apps"

Thank you all for answering!

Re-indexing did not change much, the numbers shown in Storage section remained almost the same.

For clearing things up I meant SSD memory, not RAM. I am aware how hard disk is used for virtual RAM.

Also, I am not worried about how to clean my hard disk space. I am curious why the space I just cleaned up was filled again with System and Apps storage even when I wasn't downloading nor installing anything. Could it be related to APFS?

I currently use docker a lot for creating docker images, this might take up more ram and swap. To keep things cleaner I frequently prune docker files to remove unused data, I also frequently clear cache memory.

I need Teamviewer to remote access my windows desktop pc, but used Chrome only for testing the web application in other browsers, so I can remove it. Thank you very much for the information.

I tried to re-index again, followed your instructions and saw that the Spotlight was indeed indexing this time. About This Mac Storage tab showed 5GB more free memory now than before.
