Morphology
by + far
The meaning 'used to emphasize that something is much better or greater' is directly built from 'by' as a marker of degree/difference and 'far' meaning 'to a large extent', so the combined sense 'by a large margin' is compositional. Similar expressions exist in many languages (e.g. French 'de loin', Spanish 'de lejos' / 'por mucho'), so a B1 learner who knows the words would typically infer the meaning.
Etymology
By far may come from a simple picture: in a race one person is well ahead by a long distance, so far shows the big space between them. That's why we use by far to mean 'much more' or 'clearly the best'.
