It can get quite confusing, the logic in your head is right.
The point is that events in Construct (conditions) already are checked everytick, so you don't need to add that block (it's already hidden in there).
An example of usage for everytick would be moving a sprite do the right, you can use
On Every Tick > Sprite set X to Sprite.X+1
this way the sprite will move 1 pixel to the right every frame.
