It's a fair question, but only if you also look at the experiences of Emery, Sarri, van Gaal, Mourinho and countless others while also looking at the experience of young managers with next to no experience who've also done very well.
Even of the examples you mentioned, Arteta's biggest crime is very limited improvement in league results, it's not like he took over title contenders or top four regulars. And he won a trophy in the process. Lampard finished 4th with a team that lost it's best player during a transfer ban and managed a cup final. Which suggests to me that the pitfalls are greatly exaggerated.
Experience obviously counts for something but I don't put anywhere near as much stock into it as others seem to. Finding someone who has the right tools in the locker is far more important and the far bigger mistake a lot of clubs make is not looking at this and simply is hiring someone who's coinvent, has a good CV or simply a club legend, experienced or otherwise.
It's also worth pointing out that while these guys might have no managerial experience, they have decades of football education, often from top managers and years of coaching, often alongside top managers. It's not like you're hiring Ted Lasso.
