I have the latest Mac Mini with 32GB of memory. How can it be that with only Activity Monitor open, it shows 10GB used (7GB apps / 3GB wired)?
Please help me understand why this is normal.

It's normal because unused RAM is wasted RAM. Generally macOS tries to keep RAM highly utilized. Things will be cleared out when needed. As long as your Memory Pressure graph remains in the green, you are fine and don't need to worry about the Used amount.
That is so not true. It will keep cached files as long as it can, preferring to swap to disk and compress memory before giving up cache, slowing down the system considerably. Doesn't happen on Linux.
My Windowserver is currently 14 GB, and it can't be purged. Real memory is 1.2 GB.
