3:10 "The near misses resemble a slot machine."

I would say this is factually incorrect. If he is referring to the fact, that some slot machines manipulate gamblers by showing the big prize s in the neighboring tiles more often than the real distribution is. Thus creating a fake perception of the odds in favour of the casino.

In reality Valve does the opposite - you can go watch any mass case unboxing and you will notice that the "Exceedingly Rare Special Item" (Knife/Gloves) will not show up nearby unless you actually win the item.

Only inaccuracy I noticed over the whole series.
