Mathematics is everywhere and therefore so are mathematicians. If you haven't noticed, it's probably because people with mathematics degrees or mathematical training are rarely named "mathematicians" once they enter a particular industry.

If you are good at writing essays you don't become an "essay writer", you become a journalist, a translator, or maybe a book publisher. Similarly with mathematics: the skills make you a mathematician, but different job titles apply depending on how you use them. Why the term mathematician then? Because having a sound knowledge of mathematics is extra special!
Mathematical skills are unique, can be applied to almost any industry, and are treasured by employer.

Mathematician/Game Designer: How are the games in casinos designed? Or how is your home video game made to work? Mathematicians have used probability theory to work out the chances of winning, logic to design appealing games, and linear algebra to make the characters move on the screen.

Mathematician/Financial Adviser: How is the stock market going to behave in the future? What will be the value of a particular stock in six months time? Mathematicians use equations to model and therefore predict stock market fluctuations. The complexity and dynamic nature of the stock market means a lot of mathematics is required to keep up.

Mathematician/Meteorologist: How are weather forecasts established? Mathematicians are the only ones who can get a grasp on the equations that govern weather patterns. Real world data such as wind strength, heat convection, and pollution, needs to be set up into a mathematical framework so that some sense may be made of what looks like an unmanageable amount of information and activity.
