I believe that "I know so" is only said as a gently mocking answer to "You think so?" "So" is part of the expression "think so", whereas there is no equivalent common expression "know so". So, the conversation would go

"The answer is five."

"You think so?"

"I know so."

"know" is stronger (more certain, confident) than "think".
