As for jungle seeing the enemy jungle time things perfectly as you, going for drake/grubs/crabs at the same time, having an enemy team full of invaders when you're finally doing good, etc.
Unsure if the game actually personalizes it for you specifically but perhaps more generally based on the champs selected or champ pool and looking up what champs they win or lose against the most.
Some people have argued this game still sustains it's playerbase as to not really justify 7 minute queues and such, maybe the game is trying to figure you and other players queueing out before giving you a match.
I know for sure if you accept a match then it gets denied and you get the 2nd match inv you need to reject it since doing so gives you an autofilled position or generally low quality players or your pick is banned or your previous team in champ select is on the opposite side so the game feels kinda wrong when you lose.
