How many of you lovely lady's gave birth to a child with cord around neck

So I am still early in 10w3d but it's my first so my OB told me to watch videos on youtube because we will be doing a calm birth where she counts and I dont scream and we get the baby out with less pushes and she will help stretch me so I dont tear.... and just about every video I have watched. I watch the uncensored ones ... the cord is wrapped around the babies neck... it that normal?? To me that is super scary and i always thought it wasn't common. But it's hard to find a video where the baby comes out and the cord isnt around his/her neck. Also I watched a few where they rip... and omg... bless yalls heart that looks so painful.
