The Torah laws applied to various groups depending on the specific law - some applied to all mankind, some applied only to Israelites, some applied only to Levites, some applied only to male Levites, some only applied to Levites serving as Temple priests and some applied only to the High Priest.
Certain of those laws were contingent on circumstances - the existence of the Temple in Jerusalem, for example - and some are clearly not bound by any timeframe, any set of circumstances or any specific etnnic background or social role.
Those Torah laws which apply to all men for all time were never changed, altered or abolished, nor could they be.
Those universally applicable laws include those regarding the treatment of one's own body, the treatment of one's fellow human beings and the necessity of honoring God.
