Talking about immediate family (parents, siblings) or extended family (uncles, aunts, mamus, chachus, phuphis, khalas, cousins etc)?
Parents would always support you as long as they're in sound senses. Siblings? Yes when single, depends on the spouse for future. Most of them do support anyway.
For extended family, things get complicated. They may or may not sound supportive. They can be much supportive in early days of if they got their interest vested in yours (like kids marriage), they may even support financially at times but not expecting them to do it regularly. But with time, with the deaths of binding people or weddings they are expected to fade away.
I used to live with my cousins and uncles (mamu, chachus, phophos) throughout my childhood and teens, but we barely see one or two after months for couple of hours, and hardly visiting anyone's home in years.
