Yes, unless by 'primates' you actually mean something that isn't a primate. Primates care for their young, give milk, have advanced brains and sensory organs, and have hair so yes they are mammals, as are humans.
If you mean "Are all mammals primates?" then the answer is no. Primates are a type of mammal. All primates are mammals. Not all mammals are primates. For example, cats, dogs, bears, rodents... these are all mammals, but not primates.
All chimpanzees are primates but not all primates are chimpanzees. Humans, for instance, are primates.
