The reality check

What the machines actually did with 30, across every lottery this site holds a long record for.

EuroMillions97of 104 expected−0.75σ
SuperEnalotto150of 161 expected−0.89σ

Across 5 lotteries that hold a 30, its average deviation from expectation is −0.58σ. Statistically ordinary, everywhere.

The one thing a belief about a number can measurably do is change how many people play it — and a jackpot shared more ways is worth less to each winner. That is the only real consequence, and it is arithmetic rather than folklore.
