Can someone explain this magic of this Rspec test?

It just seems like complete magic that click_link takes in a string "New Todo list" and somehow knows that it is referring to the button that has "New Todo list" in it. What if there are two buttons with this exact same string on the same page? How would click_link differentiate the two?

I assume it is looking for the < a > (anchor) elements in the DOM and then checks the string between the opening and closing tags, comparing it with your argument in the click_link method. If it finds this very string, it clicks the link. If not, it reports an error. If it finds more than one, I assume it will give you an error saying that it's "ambiguous" because there's more than one anchor element with this string.
