- You have been granted a student visa by Germany. Other visa officials will see that as a good thing, a relatively strict country investigated you and gave you a visa.
- You have changed your plans on a significant issue. Other visa officials may see that as a bad thing and consider you unreliable, but they understand that a student's plans can change.
Basically, you had the chance to go to Germany where you could have tried to overstay and work illegally, and you didn't do it. Point in your favor, but it doesn't guarantee future visa.
