It's both depending on the context.
For example, in the C major scale, the note A is the 6th note. The chord formed on the 6th scale degree of the C major scale is an A minor chord.
But we are starting with the premise that we are in C. So, the A is the 6th scale degree, so in this context the A minor chord is a vi chord ("minor six chord").
But, if we start with the premise that we are in the key of A minor, then the chord formed on the 1st scale degree is also an A minor chord. But it's the 1st scale degree, so in this context the A minor is a i chord ("minor one chord").
