The Canon mirrorless cameras do not link the exposure meter to the AF point exactly. That can be a source of confusion. Select spot, center weighted or partial metering, and it meters the center spot/area every time.
But, when you use evaluative metering, the metering follows the AF point. Its easy to see, hold the camera still and move the AF point to a darker or lighter area of a scene and watch the exposure change. I don't have a M50, but it should work the same way.
So the answer is yes and no, it depends on the metering mode and AF point/area selection. As long as you use evaluative metering, the metering will follow the AF point. The other metering modes do not do this.
