It may seem obvious but an apprenticeship in graphic design is a very different career path than the typical route of going to university and applying for a job as a junior graphic designer.
Whilst apprenticeships are not a new idea, they have been around for yonks. The Victorians were big on apprenticeships and you can read horror stories of poor little Timmy working for 16 years apprenticed to some slave driver and his mean wife. Things have moved on.
