“Warm-blooded” doesn’t mean that the organism’s blood is literally warm. Warm-blooded means that the organism actively maintains its body temperature to facilitate a consistent rate of chemical reactions within their body. Cold-blooded organisms rely on external sources of heat; sometimes their body temperatures are lower than their warm-blooded counterparts, sometimes it’s much higher. E.g. crustaceans living in underwater hot springs.
Please note that nothing in the comment you're replying to assumes that every warm-blooded animal has a higher internal temperature than every cold-blooded animal.
The only assumption is that no warm-blooded animal is among those with the lowest internal temperature. The existence of some "cold-blooded" animals that are warmer does not change that.
You may be trying to save face, but if you did know that then your initial comment wouldn’t make sense. An organism who is cold blooded has to expose themselves to heat sources and thus take on more heat damage than a warm-blooded animal.
