A measurement is not a measurement unless it can be traced
to a primary standard.
So your multimeter measures 204.5 mA when it says so
because the manufacturer of it says so.
Your manufacturer can guarantee that,
because he has calibrated the thing
against his standard ampere meter.
He knows that his standard meter measures amps
because he takes it to his national standards lab,
where they calibrate it for him.
And ultimately (if you live in a small country)
your national lab takes their standards to NIST, or BIPM,
where they do have a primary standard.

Possibly. Or the manufacturer or certifier or the national
laboratory may have a reference that they compare directly
to the definition.
