I heard people say that if you or someone got stabbed, you shouldn’t take out the knife. but why? isn’t it better to take it out?

Take a plastic bottle filled with water. Poke a hole in it with a knife and keep the knife in. The water will trickle out, but at a slow rate. Pull the knife out, and the water will leak more quickly. That’s what’s happening to a body when an impaling object is pulled out.
Based on my extensive movie research, it’s because THAT’S the exact moment the police will show up and then you’ll have to spend the next two hours proving your innocence.
Is time a factor with this question? Don’t pull out the knife and go to a hospital.
If you really are just asking, then it’s because the knife prevents your body from bleeding by plugging the hole.
In addition to what people have said about the knife plugging the hole (not so strange, it has help from natural clotting and the smaller the gap the faster clotting factors will form a seal) there is an additional issue.
A human consists of layers and layers of tissue. Skin on the outside, layers of muscle and other tissues on the inside. With the knife in those layers are fixed against each other. Pull it out and they will once again start to slide against each other and the damaged tissues will no longer be aligned, making it much harder for a surgeon to figure out how deep the injury is and find all the layers that need to be stitched up.
Fill a glass with water. Put your hand over the top of the glass. Flip it over. Remove your hand. Notice how the water stops being in the glass because there’s a hole. That is why you don’t want to remove the knife until there is something else to put over the top of the glass.
The number 1 priority for someone with a deep wound is to stop the bleeding, or at least slow it down as much as possible. One way to do this is through packing, which is essentially filling the wound with sterile material to stymie any ongoing bleeding. In the case of a stabbing, the knife itself can act as a packing material, slowing down the bleeding. Removing it would allow for more bleeding, which is counterproductive. Removing a blade should only be done when you’re in a setting where the wound can be immediately sealed by another method.
In the case of puncture and/or stab wounds, there can be situations in which leaving the object in place actually prevents further damage or faster blood loss.
as long as the knife stays in it mostly plugs the hole

The knife helps keep the wound closed vs taking it out and then it gushing blood that cannot be stopped. Better to wait and let medical professionals remove it when they have the tools to stop the bleeding and/or access to blood for transfusion.
‼️I once saw a video of a man fill a small sandwich sized ziplock bag with red liquid. He then stabbed it with a sharp pencil. A little liquid came out. When he removed the pencil the whole bag emptied in seconds. I could not find the video though.
