Yes we lose as well. I have been lucky for years, won a lot, and lost near all. We can never be winners at all the trials, we can win most of the trials, but the few loss can eat most of it. JUST care the loss not eat all wins.
Never all times play "carefully", at a no no zero, a bold short burst at the table can get a win. A table with so well 0 as 00 I would not even try. Game as roulette turn over a lot of money, the HA eats if play long and large cover of the carpet. NOZ is a lot differ, but few really understand.
