You're right in a way, but wrong in a more important way.

Charities can spend their money on administration, marketing, etc., such that very little can end up going to their chosen task. A government is the opposite. There are millions of people clamouring to whinge about any amount of waste in government. So you end up with governments being up to 6 times more efficient at delivering aid. The classic example is the cancer cure charities that deliver almost no research funding, while government grants are an excellent source of funding.
