I'm not sure such logic works in general. Summing months and days separately depends on time scale you use, are leap years and months with 28,29, 30 and 31 days are inside. If take time scale from the beginning of Excel calendar that could be

=LET(
  total, SUMPRODUCT($C$1:$C$4-$A$1:$A$4),
 DATEDIF(0,total, "y") & " years " &
 DATEDIF(0,total, "ym") & " months " &
 DATEDIF(0,total, "md") & " days")

but results very depends on from which start date you calculate total number of days difference in the periods.
