Yes, that's true.
Let check keyword statistics for USA on indeed.com:
Test Automation gives 22,100 positions
Selenium gives 5,263 positions
TestComplete gives only 90...
First of all companies are looking people for general processes and only then for particular tool.
Most of companies do not know what exactly they need. They only know that they need test automation. Some of them know about Selenium, because it is really good and (!) free.
baxatob thanks for the reply.
Searching on 'TestComplete' on indeed.com for Netherlands only give 12 results :(
Recognizable : companies just shout 'we need to start doing testautomation', but have no clue as to how to start it on a mature level, and so they follow the rest of the herd and choose Selenium... but it is really good? It's good for developers, but requires specific skillset and it's not really practical for the 'non technical' QA kind of people....
