How to cut this block using this cylinder by means of pulling it?
In the video the round extrusion was part of the same body, you have separate bodies.
It takes a little setup but I made a version of your file that cuts the cylinder as I drag it past the block. Kind of a fun little setup.
I don't believe you can make that cut with the cylinder but you can make the cut with the cylinder sketch using instant 3D.
Make the sketch you used to make the cylinder visible.
Make sure instant 3D is enabled.
click on the sketch. A drag arrow appears.
Drag the arrow thru the block.
here is the result.
Of course you could just use that sketch to do a cut extrude without using instant 3D.
Hope this helps!

As Bjorn Hulman says. That works when you have only one body. Not separate bodies.
