why do some blackjack shoes seem to have way more patterns

Lately I’ve noticed some blackjack shoes seem to go on these weird streaks where the same outcomes keep showing up. Like tons of small cards in a row, or dealer busting a bunch. Not talking card counting territory, just patterns that almost make it feel less random. This happens way more in some shoes than others, even when it’s all supposed to be shuffled the same way.

Could this be a difference in how certain dealers shuffle or cut? Or is it just confirmation bias when I’m trying to spot a hot table? Anyone else actually track this over time?
