Does skill hotness mean a high number of vacancies?

TIL [Puppet and Python are hot skills](http://www.infoworld.com/article/2685993/application-development/wanted-puppet-python-experts.html). Does that mean that there are so many jobs for those skills that:


1. Someone who is otherwise unqualified or otherwise subpar is likely to be hired on the back of average Puppet expertise?


2. If someone starts learning the hot skill now, the drought of skilled workers in the area will ensure absorption into that kind of work?


3. The number of skilled people available compared to the number of jobs available constitutes a shortage?

Say there are 5000 jobs for .NET coders and only 200,000 people applying for those jobs. And say there are 100 Puppet jobs available, and only 600 people applying. I understand how on a applicants:vacancies ratio basis Puppet is hotter, but isn't the need for .NET greater? Isn't that hotter? These numbers are made up but you get my point. Puppet isn't going to be broaching the theoretical limit anytime soon.
