Well, you can't really get experience at gambling, anyone can click the "roll" button at a dice site. It doesn't matter if you are a newbie or not, it depends on if you are lucky enough to win.
However, newbies shouldn't try poker or sports betting, as you do need skill for these games; the newbies should learn about them first before playing.
But there are really newbies who can take the risk among those danger to lose money and i think that is a wiser decision though not recommended since newbie people will face the risk to learn some helpfull strat on their next gambling journey, but one thing for them is not advisable and that is greediness they must take it out and dont bet higher than our allocate budget intended for gambling because they can lost everything they've got if they do that. And that is the one of the thoughs that gambling can maybe ok to newbies or maybe not.
