That's normal under idle conditions for it to hit pretty much any core, it's the OS scheduler doing it. Due to the scheduler improvements and Ryzen's ability to switch power states in 1ms, the cores clock up and down on demand, and so more power can be used to boost the cores in use without violating the power limits.
Under a single threaded program load it's supposed to schedule the load, starting with Windows 10 1809 I believe, on one of the cores the CPU reports as the "preferred" cores as they are more capable, which you can test by running something which is explicitly single core, such as Prime 95 one thread or Cinebench single core.
