No. Sometimes people describe a harmonized scale as a chord "progression". E.g., the key of G would be G Am Bm C D Em F#dim, which is just the scale harmonized into ascending triads.
In fact, the term "chord progression" properly refers to the sequence of chords
in a piece of music.
Naturally we can also use "chord sequence" to mean the same thing, and sometimes "progression" is used to make a distinction between a chord sequence in any random order, and a sequence which sounds like it "progresses" towards the tonic, with a kind of forward momentum.
E.g., Em-C-G-Bm-D-Am is a chord "sequence" (no clear movement forward), while Bm7-Em7-Am7-D7-G has a strong sense of forward motion that we might call a "progression", resolving to G in a "perfect cadence".
Still, this is not a terminological rule! "Progression" and "sequence" are used pretty much interchangeably; and you could make an argument that "sequence" also implies forward motion! (In fact, in classical theory, "sequence" has a specific meaning to do with repetition of a melodic phrase; nothing to do with chords at all.)
