Hatton, who is the younger brother of former light-welterweight champion Ricky, faces Mexican Alvarez in California for the vacant WBC light-middleweight crown.
"I'm going out there with everything to gain and nothing to lose - that makes me very dangerous," he said.
"I'm not out there to make the numbers up. I'm 100 per cent confident I'm going to come away champion."
Hatton, 29, added: "I'm coming towards my peak so this fight's coming at a good time for me."
Hatton insisted last week that he was deserving of the title shot, which caused some controversy when it was announced because neither man has previously fought at light-middleweight.
"I was fully deserving of a world title fight because of the way I've performed over the last 18 months, although it did come unexpectedly and it has come in an unexpected weight division," said European welterweight champion Hatton.
