There are people who will tell you their experience and there are people who won't, those who don't tell it are ashamed, there are a lot of reasons but one of them is that they don't want people to see the streak of losses and be painted as addicted to gambling.
It's very common. We only see the best bets that have wins and we don't intend to share how much we've lost or how much is our losing streak.
But when it comes to stories, there are gamblers that would be happy to share how much they've made in losses before they hitting the jackpot and their winning streak.
