That notation (1 b3 4 b5 5 b7) is used to relate a scale to the major (ionian) scale. It shows which scale degrees should be flattened or sharpened (and by how much) relative to the major scale.

So, you should start with E major scale, not E minor or E phrygian (natural notes from E to E: E F G A B C D). E major scale is of course 1=E 2=F# 3=G# 4=A 5=B 6=C# 7=D#. Because these are the notes that the famous W W H W W W H (W=whole, H=half, two frets and one fret on guitar respectively) formula produces when you start with E.

If you apply the formula 1 b3 4 b5 5 b7, you end up with E G A Bb B D, which is what you found. Because the flats in b3 and b7 cancels the sharps of G# and D#.

Surprisingly, this question hasn't spawned an answer regarding the other blues scale - the major blues. Notes constituting this are E, F#, G, G#, B, C#. In E major. Not quite as much used as the minor blues, as it essentially works only over major chords, whereas the minor blues works over major, seventh and minor chords.

Your translation of notes for the minor blues scale is skewed - they are in fact E, G, A, Bb, B, D, and can be played for just about any blues in E, but it's good to also be able to throw in those other notes previously mentioned in this answer.
