The ICJ said no such thing. Read the ruling. It said something along the lines of the "rights of the Palestinian people to be protected from genocide and the rights of South Africa to seek this protection are plausible".
The use of the word genocide in this context is just pure propaganda. There are plenty of conflicts with significantly higher human toil where this word is not used.
