Both scales are the same exact shape with the same fingerings. The difference is where you start the scale off the root note. Once your hands are positioned correctly, you will play the scale using the same shape.
The major scale is rooted on your pinky., so place your pinky on the root note, then place your ring, middle and pinky on the preceding frets. The scale will still be played starting with your index finger.
The minor scale is rooted on your index finger, so place your index finger on the root note. The place your middle ring and pinky on the following frets. The scale will start with your index finger.
Not to confuse you more, but It’s important to know if you’re playing in a major or minor key. When playing wothothers or by yourself, if writing your own songs, etc. it won’t sound good to play a minor scale or chords to a major backing track or to a song written in a major scale. When you’re practicing and doing improv, you will want to use a backing track in the same key. For instance, if you will be practicing a major scale in C, then you will want a backing track in C major also. You can search in YouTube for whatever key (root note) you’ll be playing, and and type in backing track “C major” or whatever key. The same with a minor backing track. Once you know you’ll be playing a minor scale, search for backing track, C or whatever key &minor.
