What you described is ABSOLUTE poverty(not the possibility of making that money, but actually doing so is the definition. Just the possibility would be considered a failure by chinese standards), the form of poverty(also called relative poverty) which China has fully eradicated not too long ago. China defines relative poverty much more broadly.
In short: To be considered not poor in China you have to have full access to healthcare, edcuation a relatively decent income, solid housing and so on.
They did not “pat thremselves on the back” for givcing them the “possibility” of making above 1,90 bucks a day.
