donos are kind of important too but not really a stable source of income until she has a lot of people watching at once, then she'd have her whales and a rotating set of occasional donors (but it would still fluctuate wildly - think of it as individual-based tips for service staff, supplementary at best)
currently she has ~100 members paying $4-$5.5 USD a month depending on the currency
YouTube takes a 30% cut of that, bringing the revenue to somewhere between $280-$350 USD
Sakana provides a salary, which is possibly from taking a second cut of their income post-Youtube's cut from all the membered girls to provide an equal salary or whatever, we don't know
Tenma already has what I assume is a decent job, and a monthly budget she's used to, so until she beats that with streaming it wouldn't be viable for her to go full-time, and even then there's a chance she might prefer to keep this a side gig
TL;DR
she's an adult, and she's obviously smart, she'll know if and when she should quit her day job, speculation doesn't really mean anything when we don't know her circumstances
