Your scheduled arrival is the time at which the aircraft's brakes are locked at MUC. Depending on where you are seated, you might not be off the aircraft for 3-15 minutes. If the onwards flight departs on schedule, you will not make the gate time. But, it might be delayed as well. Whether your seat is held is a different question.

Your bags are more likely to make the flight than you.

I would strongly suggest doing the research on later flights so that you are prepared to ask for what suits you best if you misconnect. Don't forget that depending on the reason for the delay and the length of your delay into OTP, you may be due EC 261/2004 delay compensation.
