No, I've been here for a little while and I can see the newbies are losing too, if you aren't a great sportcapper or specialized in poker and even then the odds are not in your favor as a newbie. Even older and more professional gamblers lose as well.
Before telling newbies to bet, ask them if they are aware that not all the time there's a beginners luck. And everyone is prone in losing so make sure that your friend that is newbie knows his possible fate in gambling. If he will only gamble for fun, it's fine but if he is amazed of the possible profit better to stop him while it's early.
Every one start as a newbie and after spending time in gambling get experience and learn skills. I think no one start gambling as an experienced gambler, I think in very beginning, or just as a newbie we need to start gambling with small bits.
Because we need to become familiar with gambling first know the nature of gambling and when we get some experience then we should increase our betting. I think in very begging everyone really lose money in gambling.
