Do I need a back tempered glass on my iphone 14 if I'm buying a case for it?

I came from an android phone and switching to apple my first btw, and I'm very excited because I'm having it delivered tomorrow, so I noticed that it has a glass back, and I don't want it to break when I drop it accidentally one day (hope not) so my main question is, do I need a rear tempered glass cover, if I'm buying a case anyways?

Note: I don't have apple care because It was bought overseas
