Out of a population of 10 million so "most" is incorrect however it is a surprisingly large number.
The phone data is partial data as it is from a single mobile phone networks out of the four. It has been since updated to 2 out of the 4 (the other two supposedly respect their customer privacy). These number are not about Paris, which has a population of around 2 millions people, but for the whole metropolitan area.
For the actual city of Paris 600 000 people left the city in a matter of days in relation to the lockdown announcement, or about 27% of population. https://www.insee.fr/fr/information/4477356
I'm unsure of what the number would be if we added the other two phone operators and the people who wanted to leave but could. But this would probably not amount to "most".
