I don't think that is even true. This may refer to the total volume of potable water. between the great lakes and Antarctica, there is lots of non-salt water out there. Easy google results show 35 million cubic kilometers, which is a rather large sphere. https://www.gigacalculator.com/calculators/volume-of-sphere-calculator.php https://www.gigacalculator.com/calculators/volume-of-sphere-... A 35 million cubic kilometer sphere would be roughly 400km across. NYC is big, but not that big.

The volume of the Great Lakes, per Wolfram Alpha [1], makes a sphere ~22 miles in diameter. The Great Lakes is ~20% of the world's surface fresh water. Your number of 35 million cubic kilometers includes the Antarctic ice sheet, but the definition of "fresh surface water" sounds to me like it intends to exclude the ice sheets from the list.
