A list of backing chords can give you probable candidates, but not the key. I made two example tunes with those backing chords.
Example 1:
Example 2:
In my opinion, in the first tune, Dm is a good ending chord and Am in the second one, but you can try it out yourself.
When you see chord progressions, they're just backing chords, instructions for accompaniment. They're not results of some kind of statistical analysis of all frequencies on a recording, and how people on average perceive the whole.
