I’ve seen several videos about drywall and I noticed a few people say they are using “hot” mud. Are they heating it up before use?

There are tons of different spackle formulas but they usually all involve a gypsum compound that cures, which is a chemical reaction that is different from drying.
Depending on the exact type of chemistry in your spackle, adding warm or hot water will accelerate the chemistry of curing and cause the spackle to harden faster. The implication is you can add further coats or get to sanding/painting quicker.
In this example the taper is usually adding warm water to a dry spackle dust to create “hot mud.”
Powdered drywall mud, also called “setting mud” or “hot mud,” contains chemicals that react when water is added to hasten hardening time. This type of mud tends to shrink less than all-purpose premixed mud but it begins to harden very quickly.
It’s slang, and has nothing to do with temperature of its mixed components.
Mud is a type of plaster used to finish walls and ceilings. It is made from a mixture of soil, clay, and water. The mud is then mixed with either fiberglass or paper to create a sticky paste that can be applied to drywall. Mud can also be mixed with paint to create textured effects on walls and ceilings.
There are two types of mud: hot mud and cold mud. Hot mud has been heated in order to make it easier to spread and apply. Cold mud has not been heated and is more difficult to work with.
