It's hard to answer these questions because you're asking like a human engineer how another rationally designed system "works" via agency and intent. Biology doesn't work that way.
But yes: the data is signalled in the form of pools of individual molecules. The messaging system uses tags to target molecules (in some cases) or just controlled spatial relase to target the messages.
The controlling system is a complex set of genetically regulated proteins and other components.

None of this is fully understood but it has been extremely successful in explaining a lot of more complex developmental phenotypes.
