Most of these programs require you to be able to clear the bureaucratic hurdles to be eligible for them; welfare reform in the '90s made many welfare programs temporary or added work requirements to them (like TANF, which is "temporary assistance for needy families). This continues today, with the Trump administration allowing states to add a work requirement for Medicaid, which in many cases would then make people ineligible for Medicaid as they would earn too much to qualify, but too little to get Obamacare subsidies for private insurance.

If you don't have a permanent address, up to date ID, and a bank account, and a job, many of these programs may not be available to you.

But I believe these counts do not include welfare programs other than those that give you cash (like Social Security benefits including disability). Other programs offer services or restricted forms of payment, which cannot be used for saving, for purchasing other things you might need like gas or transportation, and so on.
