I know next to nothing about her following. Reading your description, I can only agree.
However saying that someone is a

is like saying someone is a false human.
Granted, I could agree with the sentiment from the depth of my r̶a̶c̶i̶s̶t̶ race realist heart, but that doesn't deny the existence of such entities.
Look up the etymology of 'demon' if you like to know more.

Except it unequivocally isn't. To call an entity a God actually means something. For an entity to be such a thing it must meet certain criteria, or the word is useless.

Santa Muerta is not All Present
Santa Muerta is not All Knowing
Santa Muerta is not All Powerful

Those are the criteria for calling an entity a God. Many would love to be believed to be such an entity, many more than actually are such. In as much as they claim to be Gods and Goddesses in order to exact worship and servitude from others, their failure to fulfill even one of the necessary criteria renders them liars of the worst caliber. They're no better than conmen leading people along for their jollies. 

And so

Santa Muerta is a false goddess
human
But anon, there is only one entity fulfilling at least two criteria, maybe even all three. Yet, there are plenty of entities who were venerated as Gods/esses despite not fulfilling these criteria, including Yahweh and Shekinah.
I'm offering you a framework which should help you to expand your understanding - take it, or don't.
