Wouldn’t a camera with a constant resolution capture images of the same quality and therefore file size? How is it possible that some images on my camera can be 1.5 MB, and others 2.5 MB?

When shot in RAW, they do not.
When converted to JPG, they do, because JPG’s are *compressed* and *lossy* file formats. They try and make the filesize small by throwing away bits of information you can’t easily see. For example, it knows you can’t see a difference between three very similar shades of blue, so it throws two away and pretends they’re the same. Now there’s less data in the image.
When you start seeing the difference is when the compression went too far. It’s usually most obvious on red shades.
Because no two images are identical, you get different file sizes. Lots of clear sky? Lots of blue to make look similar. Better compression. Smaller file.
