The answer is probably both yes and no, but the roots of the answer lie in these things called "projections".

Now, maps are flat pieces of paper (generally) and while everyone believed that the world was flat, this would have been hunky dory. If this had been true, then presumably someone would have eventually discovered the edge of the world, and we could have a piece of paper precisely the same shape as the world to colour in with blues & greens & browns, and we'd have a nice precise map.

Unfortunately, the world is more like a squished sphere, and this doesn't unravel into a flat rectangle like the paper-mills produce and is nice and convenient for sticking in books. Instead, you either have to cut it into funny shapes (and you'll still have issue, but they will result in less glaring errors), or you have to stretch it out.

The typical projection is to make a cut in a straight line fro,mm the north pole to the south pole and call that cut the left and right edge of your sheet of paper. The top and bottom edge become the poles - along their entire edge as we are stretching a "point" along these edges.

The impact of this is that all the stuff close to the poles gets stretched out of proportion in terms of physical size if you were to assume a constant scale across the sheet of paper. To "fix" this, you have to have a variable scale across the map.

This can be demonstrated in reverse with a simple balloon and marker pen experiment. Inflate the balloon, draw a square on it near the "equator" where the material is stretched the most and another one the same size near the "pole" where the material is not stretched much. Then slowly deflate the balloon (or pop it, but you may lose the pieces). Now are the squares the same size/shape?

In reality, there's a standards body that has chopped up the world map into different regions of latitude and longitude, and defined a mathematical equation that maps the lat/long to an x/y coordinate in metres. And this equation is accurate to a given tolerance (typically a metre or two across a reasonably large swathe of the map), but is only valid for that zone.
