In this youtube video in French at 1:53, the French subtitles say:
Ce qui ne l'empêche pas d'être de toutes les manifestations qui dénoncent la brutalité policière.
while the English subtitles (not auto-translated, but instead presumably created by the uploader) say:
Which doesn’t change the fact that he takes part in many protests against police brutality.
A quick DeepL translation of the French subtitle gives "all", and a quick WordReference glance for "tout" doesn't produce any entry with the meaning of "many".
Is the English subtitle translation inaccurate, or can "tout" really mean "many"? If "tout" can mean "many", can you give other example sentences; and how do I know when it means "all" vs when it means "many"?
