Different contracts between Twitch partners have different levels of ad density, as well as differing amounts of cuts of subs/bits taken by Twitch. It's pretty negligible though, and could have been kinda estimated previously. For example, Hasanabi is claimed to have one of the lowest ad density requirements on twitch (1 60 second ad per 1 hour of broadcast, plus 3 minute ad at end of broadcast) which does line up with him making less than multiple streamers with less subs than him (and with probable higher ad densities required by contract).
