Well not exactly. Like a Thief who became a Hunter wouldn't be able to cast Mage spells. But anyone who was a mage and then became something else could be able to cast spells within reason. The elementals mages use to cast spells don't react well to metal unless it is specially treated with an exotic substance that fades over time. So a fully armored warrior who used to be a mage probably wouldn't be able to cast spells.

That is what has currently been shown in the novels about Mages. It is currently unknown if an ex-priest can cast Priest spells due to the spells coming from the god of light. We don't know if a priest who changed guilds would be able to cast priest spells. Same with Paladins. Dread Knights cannot change guilds so they would need to be a mage first in order to cast Mage spells as a Dread Knight.
