The government will not pay anything for you if you have a considerable chunk of savings you can pay for yourself from. You are only really considered poor if you have no savings.
It depends on how you declare your savings, even if you declare your income out of invetment of 300k it might be less than poverty line and you might be able to claim some monetary help from govt. Anyway, even if you didn’t get those, your medical and social insurance should be paid by govt.
