In Buddhism we have the notion of stream enterer which if entered leads to, in the fullness of time, liberation or nirvana. This does not mean that the subsequent lives of a sotāpanna are easy rather ultimate “success” is assured. The challenges scale with the capability of the being.
One can think of the lives leading up to a possibility of stream entrance as a game of snakes and ladders. In some lives great karmic progress is made, a ladder. In other lives normal steady progress is made, the roll of the dice. Then there are lives in which arrogance and poor choices loads on extra karma. These lives are the snakes where one starts off again in a worse position. There is a snake on square 99 {97 here}. Just when success looks possible the chance is squandered. The problem is that progress and illumination can often stimulate arrogance and poor attitude. By accumulating personal power, one might get wealth, greed and clinging. What looks shiny could be retrograde.

As one gets close to the fleeting moment of chance for stream entry the challenges get ever larger and sometimes way more subtle.
Imagine if you encountered Siddartha and failed to learn from him. Your “omniscience” somehow got in the way. That fleeting moment of chance which led you to the presence of a Buddha was missed. That is one massive Burmese python or anaconda of a snake! A Buddha could be the key to stream entry.
You missed a huge possibility for progress and were sent way back to learn all over again. A potential fate was forfeited.
Because of dependent origination or dependent arising, no fate is 100% fixed. But the general trends of karma and fate hold true. You have to cooperate with your fate in order to progress smoothly. If you are sulky and “do I have to” you won’t get ladders you will get snakes. If you are stubborn and pig-headed you will get many snakes. If you are light and easy, you will get ladders and people who help you on your way.
Some people really make bad choices, and in my experience, this is to do with them being glamoured in one way or another, by things or people. Those fond of short cuts, can find that they are anything but.
