"There are no ko threats in the opening", because there is so much flexibility and fluidity in the opening (fuseki). As a practical matter, this is closely related to the difficulty of accurately assessing the gain or loss of plays in the opening. Just about any move that could be played as a ko threat can be ignored.

Charles Matthews A proverb, but not literally true. If a ko fight occurs in the early stages of the game, then apart from local ko threats there may be only threats to play two damaging stones against opening positions.

For example

may become:

Enclosure broken through



It is almost impossible to count this type of threat accurately, though by feel it is around 30 points (?).
