does ballooning really reduces mem usage in proxmox?

i configured ballooning for our Windows KVM machines and it seems to work:

When I sum all KVM machines "Memory usage" I will get something like 40 gb memory usage (18 KVM machines).
Furthermore there are 15 LXC container on that node (memory usage something like 6 gb).

But proxmox and free -m telling me "160 gb used":

Also Htop shows the amount of total memory instead of used memory:
12,7% of 256 gb memory are 32,512 gb memory. This VM has 32 gb memory:
but ballooning seems to work, proxmox says only 1,2 GB memory used.

Any ideas?
