Gutters and columns

I might be wrong but I see Gutters and columns when I’m looking at material design.

You create gutters manually, right? Like with margins and padding.

And with materials designs or anything, the columns of design are implied but aren’t really there, right? You’ve got to design around the concept, right? Since you can’t predict screen size especially, right?
