Yes, of course that is true. It doesn't change the fact that it is considered a common courtesy, and a sign of quality writing, to define any unusual terms like this when you first mention them. It's the same principle as writing readable, self explanatory code. You write your article once, but you hope that many thousands of of people, with all different levels of experience, will read it. If you can take a few minutes to save thousands of readers a minute or two each, that is a big win. If you really want to do it right, you can link to those Wikipedia articles when you introduce the terms. After all, your reader may be on a mobile device on the bus, where it is easier to tap a link than to copy and paste or retype the term to find out what it means.
