For me, learning scales, arpeggios, intervals and modes was really just about developing the muscle memory and vocabulary required to "play music".
Years of repetition creates the muscle memory needed to give you the ability to use these tools without thinking about what they are, how they fit, and where they belong. Then the whole thing comes down to "knowing the song". I mean really knowing the song. Knowing it well enough to sing it or "play the record in you head" and then letting intuition and training take over.
If you know the song, you know where the progression is going to go.
If you know intervals, you know how to get to the next point in the progression.
If you know scales and arpeggios, you know what is going to fit and how to apply it.
If you can sing the song and have a very good sense of the melody/harmony you can build your improv from there.
If you don't know the melody/harmony and approach from just the perspective of the chord structure of the song, your solos will simply sound like a bunch of scales played over chords. Scales are not melodic. Good solos are.
Just my 2 cents.
