That holds the same way "Chaos" now means "random"
It's roots were retranslated to form our modern use of the word.
BTW, Chaos means "gaping hole"
theos (the root of theology) is God (derived from the Greek goddess Thea before Zeus and the Olympians overthrew the Titans).
thea (the root of theory) is 'to view' (as in theater).
The term "Chaos" has been used somewhat differently for about the last 25 years in mathematics. Chaotic actions in dynamic systems are different from random actions. The Kolmogorov-Sinai entropy of a random system is infinite but it is finite for a chaotic system. (A "completely deterministic" system has zero Kolmogorov-Sinai entropy.) Of course, from observation, it's a bit hard to tell "a really big number" from "infinite."
One way to look at the classification is to notice that random systems cannot be predicted even if one knows the initial conditions. Determinist paths can be predicted even if one does not know the initial conditions. Chaotic systems would be deterministic but one isn't able to get the initial conditions. It's a bit of a change in usage; some people still lump chaotic and deterministic systems together.
