No, without prior work experience, you can apply to courses in Germany. But, for some courses, they do keep a requirement of minimum 1 year experience. It basically depends on the course. The main thing Universities look into is your GPA. If you have good GPA, then consider that your 50% of admission is assured. Rest depends on profile like skill sets developed, internships, projects handled and incase of some courses (the number of journals published)
In general, the Universities look into your GPA, your TOEFL/IELTS Score, Your SOP and LOR's obtained. If you have Good GRE score, it improves your chances. But, it is not mandatory. Also, having knowledge in German helps to increase your chances, especially in courses where there is German electives. You need B-1 level German.
