People who have not much knowledge or new in blackjack could lose more than red black because skill and experience sometime help to win in blackjack (though luck is always everywhere). But it the red black Luck is play a vital role to win or lose.
I think that usually the opposite is true. People who play the first time without knowledge win more because they purely play with luck and not "skills", "knowledge". Skills are useful when you play poker in real life, there is an involvement of human psychology, simulation, etc.
If cutting card cuts half of the shoe in blackjack, then it has no idea to count the cards. If you can't count the cards, then what advantage do you have? One thing is to focus on side bets and wait for your luck to shine there too. But there is a reason why there are limits on tables between certain ranges.
In blackjack you can't win for a one reason: You are the first one who makes decision and dealer is the last one. If you fail, dealer automatically wins, doesn't matter whether he/she gets busted or not.
Btw it's very funny how some people follow the dealer and stand on 17 / draw on 16, haha.
