In Photoshop, ctrl clicking doesn't select the shape all the way to the edge. Is it possible to increase the selection radius?

Question

Adobe Photoshop

Why, when selecting individual shapes via ctrl click, the selection does not reach the edge (The brush is hard, but still, when you zoom in, you can see that the edges are blurred). If you draw shadows for these shapes on a separate layer, using selection via ctrl click and subtraction from selection with the help of a magic wand, then a gap of 1-2 pixels is visible between the shadows of individual shapes. How to make the selection through ctrl click capture the entire form to the edge?

Answer 1

Didn't quite mean it. The fact that you can adjust the selection is understandable. The question is, is it possible to set the selection in such a way that ALWAYS ctrl click selects the entire shape, taking into account neighboring pixels (those that are blurry), and not adjust the selection after each ctrl click?
