Supposedly there are thousands and thousands of vacancies, but if you actually look, most are agencies. You don't so much apply for a vacancy as get lured in to sign up for an agency. They might or might not then put your name forward for something, and it might not be suitable if they do.
And most of the jobs that are not actually just imaginary fronts to help an agency get your details on file, require ownership of a vehicle.
AIBU to believe that there are actually far far fewer vacancies than the news headline figures are suggesting.
I would guess 10-20% at most
