Three black people, two men and one woman, in the middle of a small, rural street, are piling up items on top of a taxi cab with a net dangling down on top of the windshield, while two children and two other people are nearby.
Many people load up a taxi
If three people are piling items on a taxi while four others nearby are not, then it is more appropriate to claim that some people are engaged in an activity rather than many people.
The three black people could be entering the taxi, but the children and two other people nearby does not mean many people are helping load up.
Many people doesn't necessarily mean three people.
