And yeah I think it’s always happen that good players house edge is less than a normal/not good players imo.
So bad players: use RED or BLACK if you want a lower house edge 
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.
