She currently has
437 Patrons and tiers for $2 and $10 per video she makes.
She's had her Patreon since April 2014 and she's also used it for fund raising for things like specific movie reviews. She currently has 285 videos listed on her Patreon (so about three every month).
She is very active on her Movie Nights Youtube channel, currently putting out about 5 videos a month or more (though some of them are livestreams that she presumably doesn't take Patreon money for).
On top of this she has the revenue from any videos she runs advertisements on and stream donations (if she accepts them).
It's difficult to know how much she's making because of the large difference between the pledge tiers - she could be low-income to upper-middle class. She isn't poverty level and shouldn't have issues paying rent on a small apartment in an OK area.
