Why is it that some phones today have cameras with hundreds of megapixels but advanced DSLRs and Mirrorless cameras have only 64?

Question

What are megapixels? How do they work? What is the difference between a 64mp mirrorless camera and a 24mp mirrorless camera of the same brand?

Along with what the others have said, another reason is that DSLR have acces to a whole library of lenses, including zoom lenses and telephoto. Optical zoom is better than digital, but more megapixels equals better digital zoom. Phones are small and limited in optical capability so the try to compensate with more megapixels.
