Sure you didn’t see anything different ? Please Supply your blend file
After boolean difference, delete cylinder or restric its render view.
If you want to cut a hole you need a mesh that matches the geometry of the hole. The ends of the cylinder should be open and the normals should be facing the inside of the hole. A closed cylinder with normals facing outward would not be a hole, it would be a peg.
And .blend file confirms it. Boolean behaves like it does because of inverted normals.
Top viewport:
Front: face directions in the original
Back: working boolean when normals are made consistent and pointing outwards by selecting all in edit mode and ctrl+N
Bottom viewport:
result without a boolean
