Why are they swearing so much on Apple TV?

I subscribed to apple TV to watch few shows that I liked, one of them was Shrinking about therapy, and I have never heard so many swearing on TV in my life, so many fuck you this and pussy and cock that , I asked AI why are they swearing so much on Apple TV but not Netflix? And it said that they assume people talk like this in real life? I am surprised cause none of the people I know talk like that, it's very uncomfortable to watch because sometimes our son comes to the room and hears it, and the last time he said the f word after hearing it on the show, one of the characters said I am the fucking momma and then my son kept saying I am the fucking momma , I immediately had to lower the volume and just read the subtitles.
