What does the latin phrase "deus ex machina" exactly mean?

Hi! Thanks for the question.

I have found the resources which explains this latin phrase.

"Deus ex machina, 'God from the machine.', In the end, all things are
settled."

"Latin Phrases and their Applied Meanings"

"The Latin phrase deus ex machina, literally "god from a machine",
referred originally to the practice in classical Greek and Roman
theater of lowering a god to the stage, usually on a crane, at the
climactic moment to dispense godly wisdom and order to the messy
mortal actors beneath. The deus ex machina was also much in favor
during the Baroque period in Europe. In modern times, the phrase
refers to the unexpected appearance of a character who provides an
unlikely resolution to a problem."

Here, also, is Gilbert Rule's philosophical interpretation of the
phrase:

"Rule argued that the mind is not a non-physical substance residing in
the body, "a ghost in a machine," but a set of capacities and
abilities belonging to the body. The "ghost in the machine" is a
derogatory term coined by Ryle to abuse Dualism - the theory that
human beings are comprised of a tangible body and an intangible mind.
It is the notion that a person is an ethereal soul that inhabits a
physical body. The mind/soul continues after death, enjoying or
suffering a conscious existence, just minus a body that can interact
with the material world in space and time."
