Yes. The to_i method is called on user_input, its result is passed as an
argument to the include? methods of (1..100) and the result of that is
used for the elsif.

blubb.include?(bla) returns true if bla can be found inside blubb and false
otherwise. In this case it returns true if user_input.to_i is inside the range
1..100, i.e. if it's a number between one and one hundred (inclusive).
