Good news: This is entirely expected and there is no cause for worry at all.

The kernel will use any idle memory for disk cache but gives it up easily at need; you can consider it as "free" memory. It quickly tops the charts on any lightly-loaded Linux system. This just means the memory isn't being used for much else.

"Free" is a somewhat misleading title and just designates wasted memory which is being used for absolutely nothing whatsoever, not even disk cache.
