Visibility controls in Blocks configurations form are missing help text in Drupal 8 .
We had this help text in Drupal 7 (Which actually helps non-tech User in understanding the feature)
PFA - Screengrab for reference
I propose to have it added for 'Content type'& 'Roles' Visibility controllers.
Cheers,
SwapS
Update: Patch available for 10.1.x
