No, this is not "unfathomably good luck", this is how the system works. Most of crimes are repeated crimes, most of the criminals are serial criminals. People who obey the law, then break it once, then obey it ever since -- are very rare and even if they're not caught I wouldn't care much anyway.

And if you're a normal criminal doing your criminal stuff day after day and year after year you'll make mistakes. One of them will get you caught.

Never in the history of humanity did the law enforcement cast a net that caught 100% of crime, it always had been the game of probabilities, luck and persistence. Steal once and you'll likely walk away. Steal every day to make a living and you'll get caught many times in your lifetime.
