Assume People ABC and umbrellas ABC
If two people get the correct ones, then the third person will get whichever remains, which by definition must ALSO be correct if the other two are correct.
If person A gets Umbrella A
and person B gets Umbrella B

This is also correct
Therefore it is impossible to only get TWO correct
