"An insurance bet doesn't help you win or protect your hand, it only allows you to push if the dealer does have a blackjack. This bet has a huge house edge and is never recommended."

"Since nearly all bets in the casino carry an EV under zero, you can't only search for positive EV bets. Play the bets with the smallest casino edge and avoid the ones with the largest."

"Casinos are smart, they know that luck alone will get you nothing in the long run. That's why they trust the math of casino games while losing players rely more on luck."

"The long run, so to speak, is the expected amount that you would win or lose if you played the game long enough to equal an average result. This is expressed as the EV, or expected value."

"The roulette wheel is always kept spinning at a constant rate, even if no one is currently playing. The ball is spun in the opposite direction in order to ensure more randomness in the result."
