Conditioning statistics
On the discrete level, conditioning is possible only if the condition is of nonzero probability (one cannot divide by zero). On the level of densities, conditioning on X = x is possible even though P ( X = x ) = 0. This success may create the illusion that conditioning is always possible. Regretfully, it is not, for several … See more Beliefs depend on the available information. This idea is formalized in probability theory by conditioning. Conditional probabilities, conditional expectations, and conditional probability distributions are … See more Example. Let Y be a random variable distributed uniformly on (0,1), and X = f(Y) where f is a given function. Two cases are treated below: f = f1 and f = f2, where f1 is the continuous piecewise-linear function and f2 is the See more • Conditional probability • Conditional expectation • Conditional probability distribution See more Example: A fair coin is tossed 10 times; the random variable X is the number of heads in these 10 tosses, and Y is the number of heads in the first 3 tosses.

Super high condition number would mean that some variables are highly correlated. 70 is not that big of a condition number to me. High or low condition number doesn't mean that one correlation matrix is "better" than the other. All it means is that variables are more correlated or less. Whether it's good or not depends on the application.
