This reminds me a story I have heard about Amma (Mata Amritanandamayi Devi).
There was a brahmacari, a celibate monk, in her ashram. He found out that his chart said that he was destined to get married, but he really didn't want to get married and he was very worried about this.
At that time they were making a movie about Amma's life. When she was young her parents tried to get her married several times, though she refused and destroyed those plans by various means.
The brahmacari in question was called to the movie set ond day and he was given the role to play of one of Amma's potential suitors.
So in that way he experienced a part of his karma, but wasn't required to experience the whole thing, i.e., a real marriage, since he had decided rather to become a monk.
This and other stories are often told to show that the guru can change one's fate, though usually the person still has to experience something of that fate.
For example, there was another monk who wanted to visit home, but Amma told him to wait. One day, he was sitting and was bit by a snake, but Amma was right there and she was able to prevent him from dying. Later they looked at his chart and his death was predicted that day. One could say though that by entering the ashram he had renounced the world and that was the death that was foretold.
I think the more conscious we are the nature of the experience changes and we have more opportunities available to us.
One year in my Varshaphal I had Venus DB in the 4th house. Around the time this was activating I was in India and I had booked a cottage in the Himalayas. I arrive and it was sort of ok but moldy, the first night there were rats running on the floor all night long, impossible to sleep. I had intended to stay for over a month and the landlord was asking for all the rent. I felt I was getting swindled so the next day I left to a nearby hotel and messaged the landlord about the situation. Instead of being irate he told me I could have an alternate lodging on the property that had no rat issues and was a much nicer situation so I went back. I see this as the Venus DB in the 4th there was some fated event to find oneself in debilitated home dwellings, but I didn't have to be confined there and since I didn't get angry I could actually negotiate for quite nice lodging in the very same place.
