Almost agree, with my 2c:
True, both are words to describe a particular complete sequence of notes, out of which one can build musical phrases.
The only slight difference to me is that when people say "mode" they often say it in a context like "scale XYZ is a mode of scale ABC", implying that two scales are related because they contain same notes, but in different sequences.
To describe a standalone note sequence, IMHO, both, "scale" and "mode" are interchangeable.
