How this works

Numbers are picked using your browser's cryptographically secure random number generator (crypto.getRandomValues), not a weaker general-purpose random function, so the results are genuinely unpredictable. "No duplicates" is only possible when there are at least as many numbers in your range as you're asking to generate.
