To "worship the ground someone walks on" in this context is an idiomatic expression that means to greatly admire or love someone. It does not mean to literally "worship the ground", but it means to admire someone so much as though even the ground they walk on is precious and something to be worshipped. Ex: People are obsessed with celebrities. They worship the ground they walk on!
