Hello Carl, and welcome! You don't have to reserve seats for this trip. For many connections, it's not even possible. You've interpreted the timetable correctly. The symbol 'R' indicates that reservation is possible; an 'R' in a rectangular indicates that seat reservation is obligatory. If no R is displayed, this means that you can't reserve seats.
Does that answer your question?
