You've got the idea. Let's look again in more detail.

B (1.5 steps) D (1 step) E (1.5 step) G (1 step) A (1 step) B

Therefore:

B (1st - root)
D (minor 3rd)
E (4th)
G (minor 6th)
A (minor 7th)

This is a group of 5 notes, therefore pentatonic. This group of notes has minor 3rd, minor 6th, minor 7th scale degrees (instead of major scale degrees), therefore it is a minor scale.

So, you are right, that group of notes (B, D, E, G, A) is found in the B minor scale. It is 5 specific notes from the B minor scale.

B minor diatonic:
B - (C#) - D - E - (F#) - G - A

I also pointed out that you can regard any note as the root note and then proceed to figure out the interval distance from that root note to each of the other notes in the group.

Doing this shows that your group of 5 notes can also be part of other scales.

E minor diatonic:
E - (F#) - G - A - B - (C) - D

E minor pentatonic:
E - G - A - B - D

G major diatonic:
G - A - B - (C) - D - E - (F#)

G major pentatonic:
G - A - B - D - E

C major diatonic:
(C) - D - E - (F) - G - A - B

Make sense?
