I disagree. Gygax was discussing a save-or-die mechanic. In 5E, it's all HP-based. Gygax's statement as quoted is irrelevant in 5E, unfortunately.
He was discussing saves and giving an example of poison. Poison will only happen if the poison gets into the body, so there needs to be a scratch. 5e drow poison just doesn't have a save. 5e spider and scorpion saves work just like he laid out.
The only real difference between the two editions is that 1e poison saves were almost always death saves. Now they do damage. The method of forcing the saves in the two editions is identical, though.
