Read my previous reply regarding 8 triples out of ~1548 draws. What's the odds of being drawn 8 times instead of some value towards 15? Probably low single digit percentage. Your point is well taken regarding range, but keeping it simple for readers.
In the ideal, perfect world, computer RNG is just as good as balls. But in the real world, time and time again, lottery computer RNGs have come up short for various reasons, including outright mis-configuration, leading to skewed results. To make matters worse, in all the instances I've read of, it wasn't the lottery that realized there was an issue, but rather players who noticed something amiss.
There was a chat on LP here awhile back with a top lottery official. I asked whether the computer source code / programming for their lottery RNGs was available to the public, and his response, to paraphrase, was "of course not". There's little to no transparency; blind trust in the equipment lotteries use to draw numbers. Computer RNG games (slots, video poker, etc) located in physical casinos (Las Vegas and Atlantic City, in particular), by and large, are seemingly more scrutinized than lottery games.
All this talk of randomness illustrates how difficult it is to get ahead playing the lottery unless one very lucky. No system, strategy, etc alone will overcome a 50% house advantage barring an exploitable flaw, security breach, etc.
