Major and minor pentatonic scales can use the same shapes, but they do not feel the same. The difference is the tonal center: where your ear hears home.
Major pentatonic is 1, 2, 3, 5, 6. Minor pentatonic is 1, b3, 4, 5, b7. Both scales have five notes, but the intervals create very different moods.
In C major pentatonic, the notes are C, D, E, G, and A. In C minor pentatonic, the notes are C, Eb, F, G, and Bb.
A minor pentatonic and C major pentatonic contain the same notes: A, C, D, E, and G. The shapes are identical. The difference is whether A or C sounds like home.
This is why the same pattern can sound minor over one progression and major over another. Your target notes and backing chords decide the sound.
Minor pentatonic is common in blues, rock, and heavier lead playing. Major pentatonic is common in country, pop, gospel, and brighter blues sounds. Many players blend both over dominant blues progressions.
For a simple test, play A minor pentatonic over Am, then play the same notes over C major. The notes did not change, but the center of gravity did.
Relative major and minor pentatonic scales use the same notes and shapes, but they have different roots.
Yes, especially in blues and rock. The trick is resolving phrases to chord tones so the mixture sounds intentional.
