People who passed in 7 lessons or something stupid like that either: drove with parents or friends for more experience or pick up real quick.
You always see it in life, some people take to stuff easily as if it's second nature, whilst the majority do not.
Do not base your lessons and driving experience trying to do it as fast as possible, I did that and caused my confidence to really drop heavily.
Take however many you want, and listen to what your INSTRUCTOR says, not what your friends or family say.
I had around 60 hours, and drive fine and confidently. Had loads of people tell me I should have passed a lot sooner. I had no driving experience with friends or family either.
Would you rather have a few lessons, take your test, maybe pass by some miracle or most likely fail and have it dent your driving confidence forever? No brainer really.
