because 'people' is the possesion of 'thousands'
It's technically not a genitive of possession, it's a partitive genitive. English 'of' expresses both ideas though, so it's not a problem.

The thousand ran quickly
Why would 'ran quickly' be in the genative?
'Ran quickly' is a verbal phrase, it doesn't take case endings like a noun. You could say "The thousands of people ran quickly" and people would be genitive. 'Ran' is the verb and 'quickly' is an adverb modifying 'ran'. Also, Latin 'mille' which means '1000' doesn't take a genitive. Only the plural 'milia' 'thousands' does. So, "The thousand men" would be: mille viri
, but "thousands of men" would be: milia virorum
. English idiom is similar, we say "a thousand men" not "a thousand of men" and likewise we say "thousands of men" and not "thousands men".
