Most lotteries use the "bubbling box of bouncing ping-pong balls" to pick their random numbers.

As I understand it, most lotteries have several sets of balls, and pick a set "at random" for each drawing.

To prevent folks using statistical analysis to pick the balls most likely to win, they perform mix 'n' match swaps between sets from time to time.

Of course, there have been attempts to out-random the system-- there was at least one case where the miscreant injected water into the balls he wanted to 'lose,' so his choice of winners would have a better chance of floating to the top.

So, my theory is,
pseudo-random number generation has been more than adequate for
business solutions. i.e. picking the lucky winner of $millions.
