Case statements can be modelled with if-else chains
but they are not the same internally.  Case statements
are usually compiled as jump tables, rather than as a
series of if-elses.  This is hugely faster than if-else
on average.

However, in Guido's defense, I will also point out the
primary use of case statements is to select alternatives
based on a type flag - which is not needed in an object
oriented language.
