@square root of 2:

I’m not sure why nobody seems to understand the question. It is a good one which I have pondered myself. I don’t usually bother with online forums but since your actual question isn’t even being discussed I created an account just to post this reply. Unfortunately, I can’t reference specific sources for what follows since it is a composite of various shiurim (mostly on chassidus and kabbalah) and divrei torah I’ve heard over the years but it should, at least, provide an approach which you can research separately.

In order to present this answer there is some background information that needs to be laid out first:

1: In the initial creation of Adam the souls of all mankind were included in his unified master/root soul which was later fractured into individual souls.

2: When Hashem shortened the life span of mankind to 120 years the total life span of each person wasn’t truly diminished it was divided across multiple lives/gilgulim (e.g. if person x were to live 1000 years they could now instead have 10 lives of 100 years each). The Arizal taught that every person has at least 3 gilgulim since they have to perform every mitzvah in machshava, dibbur, and maaseh. And that most will have many more… some may have hundreds. From what I’ve seen, the popular notion that a gilgul is only a rare occurrence and a form of punishment is not accurate.

3: Geihinom and all the various forms of punishment in this world and the next are not simply punishments and don’t last eternally. They are more of a cleansing procedure which corrects the souls subject to them. There are mepharshim who explain that (except for possibly a select few throughout history) every jew will eventually have a personal redemption and merit olam habbah. I’m not clear on whether it similar would apply to goyim as well but I think it makes sense to say that it would (although, they may only receive their eternal reward through jews).

In light of this, I would say that indeed Hashem doesn’t create people who will fail entirely. Some just have a longer, harder path to success than others. Some need multiple failed iterations of life to learn the lessons that will ultimately allow them to succeed at a future point. We see their failure as being complete because we only have one piece of the puzzle.
