A high GRE score is just one of several factors that are taken into account by Admissions Officers.
Other factors that universities look into are:
Your CGPA and transcripts / mark sheets
A well-written Statement of Purpose (SOP)
Appreciation from a higher up or professor by means of Letters of Recommendation (LORs)
Projects, Work Experience and Paper Presentations.
