Several fields have tiered roles where bootcamps/community college programs are used to fill some of the roles. Several of these are now considered trades jobs, like electronics repair or certified nursing assistant. Depending on the regulations there might or might not be a path from community college program to an advanced role in the field without a college degree. In most of the world, you can't go from a CNA to an RN (Registered Nurse) or an MD with just experience.
