I am unclear about the part where it has been stated that entropy is a
count of the number of possible states the system can hold.

If I understand that correctly, it would not matter what system it is, if it
is a complex weather pattern, water molecules in the ocean, thermodynamics in
a volcano, an explosion inside a tank, or just one CO2 molecule inside a
balloon. They will all have an infinite number of possible states, some
more infinite than others (lol) by order of volume, won't they? The entropy
will exponentiate quickly as the number of elements in the system increases, won't it?

So, if that is the case, how does a measure of that number of possible
states even matter, since it will always be infinity?

Also, it it possible entropy is not a measure of how the system got
"disordered" so much as it is just got rearranged, or moved differently?

For the sake of another example, years ago I worked for an oil shale
development company. The engineers and scientists who invented the patented
process (the only one in the world that ever worked) told me that they
never fully understood what occurred thermodynamically inside our retort.
However, they knew enough to make it work economically. Pour oil shale
into it, add heat, remove shale oil, carbon, and off gases. So, to the
human mind it is orderly enough to be practical, just rearranged and then
diverted physically.

Another example might be the Chicxulub asteroid impact event 66 million
years ago. The earth remained in a fairly steady state by geologic standards,
the asteroid struck, entropy increased, entropy decreased, a new steady
state started. I watched a great Netflix documentary about it last night.
It is called "Day the Dinosaurs Died." Scientists have drilled cores out
of the impact site (down 1/2 mile) that depict the layers of matter before
and after. Really cool. (https://www.netflix.com/title/81121175)
