Why df doesn't show accurate used space?

[raison]

When I run df -h, I get the following:

Why is it only showing 11Gb used?

I would assume because only 11GiB is used.
What does it show for the other file systems?
APFS containers have volume sharing so that right there is probably the rea<d-only system volume, which would make sense to not show higher usage than that

The screenshot shows I have 155Gi available out of 466Gi, so it doesn't make sense I've only used 11Gi.
Finder does show I have 151GB (not Gi, not sure the difference) available, so I hope that's the accurate free space I have?!

Re-read what I wrote about APFS container space sharing

GB is GigaBytes. 1GB = 1 billion bytes.

GiB (or just Gi) is a GiBiByte. In other words it sticks to powers of 2.

In addendum to the above; If you look here at my output:

The volume at root / also only shows 14GiB used; But the usage is actually coming from disk1s2, which is the same physical disk as disk1s1s1 which is tied to root. The system volume is technically two volumes; A read only system volume and a read-write data volume. What you see when looking here at / is the read-only system volume. From a usage perspective it's transparently linked with the data volume.

Ah, thank you for clarifying that!

No problem, mate
