This depends on your ticket. The normal tickets are fully flexible. Reservations are of course linked to a certain train but the ticket itself remains valid also for other trains (exact date is printed on your ticked).
If you have a discounted ticket they are most of the time only valid for a certain train. Then will you will have to pay the full rpice in the worst case. Maybe you are lucky as a foreigner but remember: We Germans tend to be very correct
