Solution 1

It's partly terminology. People use the word "worker" when they mean a thread that does not own or interact with UI. Threads that do handle UI are called "UI" threads. Usually, your main (primary) thread will be the thread that owns and manages UI. And then you start one or more worker threads that do specific tasks. These worker threads do not modify the UI directly.

My 5, but your last sentence looks incomplete: ...directly ...but they can use the methods...
See my Solution which I added exclusively to fill in some vacuum you left with this sentence :-)

Solution 2

Imagine I continue the Solition by Nishant:

These worker threads do not modify the UI directly…

…but they can use the methods Invoke or BeginInvoke of System.Windows.Forms.Control or System.Threading.Dispatcher. See my past answer where it is explained in detail:
Control.Invoke() vs. Control.BeginInvoke()[^],
Problem with Treeview Scanner And MD5[^].
