Could a job as a HVAC/Installation helper lead to becoming a full fledged HVAC Tech?

This is a career I've been looking to getting into, I don't necessarily have the time or money to go to school to get a certification.

However I do see a lot of helper jobs in my area and I was just wondering if those typically lead to being able to become a Technician?

Thanks in advance.
