First, Professional tools may not be the most cost-effective and popular tools in the real industrial world that is highly driven by cost and budget.
In big MNCs, tools are usually contracted for many inter-corporate interests due to project collaboration and agreement. Therefore you probably find so-called professional tools like Cadence Concept/Allegro/Spectre and many more.
In small and medium-sized firms, it is a mix of both depending the design team and their preferences, and the point of time at which the license agreement is valid or expires. Firms like this is very concern about high budget and getting locked to proprietary tools. You may find Protel DXP, MentorGraphics PADS Power PCB or other smaller CAD tools. Do not be surprised that you might caught them using cracked or pirated versions.
From here, you probably can guess where you want to channel your energy in learning the CAD tools to fit your so-called right job.
An advice to add: Learning the tools is like learning to play a new computer game. The basic design guidelines, practices and tricks in designing good PCBs for performance and low-cost is still the most important. This has little to do with CAD tools.
