Yes, the 7th chords (major 7, minor 7, and dominant 7) have four different notes (1, 3, 5, 7) and can be arranged in any order. These are great 'target' notes to end phrases on. Major and minor chords have three notes (1, 3, 5).
I hope this helps! Consider taking a live online lesson from me to dial in these concepts in more detail and musical examples. Here's the link to my live online teaching availability:
