Hello I have a question about financial support section of dependent child resident visa

in immigration homepage, they state if you're between 21 - 24 I need to rely on an adult for financial support

but there is not enough info about what is that financial support means

it says

When we assess if child relies on an adult for financial, we’ll look at whether:

the child is working, how many hours they work and for how long they’ve been working
the child has any other independent means of financial support
the child is living with his or her parents or another family member, and how much support is provided
the child is studying, and whether the study is full-time or part-time.

but never state how much salary can I make or how many hours can I work etc

does anyone knows where I can get specific info about financial support?

Thanks
