The distinction between a 'true' fan and just a 'fan' is a vague one. If a creator has a total audience size of 1 million, you can bet that less than 1% of them are giving the creator any amount of money, even 1 dollar. Does that 1% count as their true fans? The folks with thousands of paying subscribers, or tens of thousands, have audience sizes to match.
Given that less than 1% pay anything, what percent of those do you think pay at least 20x the normal amount ($5 -> 100$)? Many creators make this somewhat visible by highlighting their contributors and the air is quite thin.
To make a long story short, I disagree with the concept because it paints a very rosy picture of the situation and doesn't match reality much, if at all. If you had 1,000 'true' fans you'd probably end up with $2,000 a month after taxes/platform fees/expenses. And of course, that assumes that you're able to consistently monetize through a subscription platform. If you had to sell individual products to get there it would be even worse.
