One sample is hard to read because even low odds can happen. Picture the following statement: "The chance of life forming anywhere in the universe over a 100 billion year period is equal to 1 in Graham's number". If this statement is true then it is incredibly unlikely life forms in our universe at our current stage exist. Low odds can occur and the only reason anyone is here to observe them is because they did occur. Since we only know of life forming once we cannot make assumptions about the odds of it happening.
