WRONG! it depends on how the armature is set up. Hence a generator makes DC. It is all about efficiency. That is why we have AC into the house rather than DC while most electric devices, excluding MOTORS (can be set up for either), utulize DC. Voltage drop of DC over AC is tremendous. It is more efficient to re-convert it back to required usage. And an electric motor can be made to PRODUCE current but only the same type as it is made to use.
