Both Canon 4000D and Canon 100D have 18.0 MP resolution sensors but Canon 4000D's sensor is APS-C (22.3 x 14.9 mm ) and Canon 100D's sensor is APS-C (22.3 x 14.9 mm ).
Since Canon 100D's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon 4000D.
Below you can see the 4000D and 100D sensor size comparison.
Canon 4000D and Canon 100D have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture.
