Risk to Riward ratio VS Payoff Ratio

Hi dears

A beginner here.Would anyone please show me what the difference is between the following?, as I have seen in different lessons which show them as the same thing .However,I know the explanation each of them.
For instance, in the table of Risk Of Ruin, could we use the following exchangeably?

1.PayOff ratio
2.Risk to Reward Ratio

Any help would be greatly appretiated
