Both are (horizontal) measurements, so they are commensurable and
additive. Where they differ is in application.
An inset applies to all output lines, period.
An indentation applies only to a thing called a "paragraph". The
various paragraphs types are distinguished primarily by where they apply
indentation to their lines. As I put it in the groff's ms(7)
documentation, which presents a similar matter...
groff_ms(7):
Paragraphs
Paragraphing macros break, or terminate, any pending output line so
that a new paragraph can begin. Several paragraph types are
available, differing in how indentation applies to them: ... to the
first output line of the paragraph, all output lines, or all but
the first. These calls insert vertical space in the amount stored
in the PD register, except at page or column breaks, ...
