Cracks in Cement Floor of Shed

My house has an attached garage similar to this:

The garage has rooms above it, not sure if that’s worth mentioning but I’ll note it. Out the back of the garage where the house would normally end, it extends out into a shed.

From a side view of the house it looks something like this:

The garage and shed have different cement floors (slabs? not sure if I’m using the right terminology there), there’s a clear separation of them and they’re different colors; for example, the garage is darker grey than the shed’s floor.

Anyways, today I noticed for the first time (doesn’t mean they haven’t been there for awhile) some cracks in the floor of the shed:

The only other characteristics of cracks that I have is that they’re fairly shallow.

Reading online, some cracks are OK, some cracks are warnings, cement cracking is inevitable, etc. Are these something I should be worried about?
