I learned all my lead guitar technique alone, just finding each note on the guitar and practicing the licks, the timing, and thinking about the notes I was playing on top of the chords.
You can use these videos as a shortcut - you don't have to find each note by ear. Instead, use the visuals of the guitar and the on-screen tab to make it much easier.
Repetition is the key - repetition of meaningful licks... not boring scales alone... phrases that automatically develop your speed and technique as you strive to play them in time.
