My understanding of vocal technique is limited but the range is different depending on whether you're using chest voice or head voice. A lot of people could probably reach the pitch in that line of 'These Days' using head voice but if you were to listen to it on it's own without the track playing in the background, the voice would be weak and nasal.

Part of proper singing technique is to expand the range of your chest voice in order to reach notes that you'd previously only be able to reach with head voice. Chest voice is much more powerful and appealing to listen to.

After that, there's falsetto which only has very limited use before it becomes really grating.

Everyone has to resort to head voice to hit their highest range but practice and development of good technique means that you have to resort to it less and less.
