It was certainly true for an older generation. The European settlers spoke French, and some in and around the French-controlled regions adopted French as a daily language, particularly those dealing with to the colonial government. This was true until the return of the territory in the 1950s. A few families have probably carried on speaking their home language. But in absolute terms, it's quite rare. There were probably fewer than ~100,000 native French speakers in India at the peak, and I believe the majority chose to move to France when the territories were returned to India.
