Questions about the I–IV–vi–V progression

Is 1-4-6-5 just 1-5-6-4 rotated?

They share the same four chords, but the order changes the feel completely. 1-5-6-4 leans on the V early and lets the vi sit in the middle. 1-4-6-5 opens wide on the IV, then drops into the minor chord, so the minor moment arrives as a contrast rather than a resting point.

Why does the Am chord sound sad here?

Am is the relative minor of C major — it uses only notes from the C major scale but centres on A instead of C. Coming right after the bright F chord, that shift of centre reads as a dip in mood, even though no note outside the key has appeared.

Can I play this in other keys?

Yes. The pattern is I–IV–vi–V, so in G major it becomes G, C, Em, D, and in D major it becomes D, G, Bm, A. The bass motion and the placement of the minor chord stay the same; only the pitch level moves.
