Good call. Looks like you're right. That chart is a bit weird to extrapolate from without much context. I'm not familiar with this platform at all before this thread so I looked her up. Currently 3031 fans and subscriptions are between $9-15 per month depending on how many months you buy in advance. Lets just say the average price is $12 x 3031 = $36372 for this month so she pockets around $29,000 pre tax from just subscriptions. The platform also gets her additional income for the month like PPV Messages and tips which is actually a lot of additional income(20% of her totals so far).
Lets just say she just maintains her subs(doesn't gain or lose any). She might be making $35,000 per month pre tax for 2020. So yes she's on target for well over 300k.
