These are considered covers because the instruments, melodies and vocals are the same except the lyrics are different
It's a clear parody but it's not quite an interpolation. Weird Al has a lot of songs like this where he parodies an artist's style without actually copying the songs exactly. He changes the riffs or melodies enough that he gets sole writing credit but you know what songs he's referring to.
Do sections of Weird Al songs that are clear parodies of other songs count as sampling? For example, the end of I'll Sue Ya which is a clear parody of the end of Killing in the Name; can this be added as a replayed sample?
Weird Al is the best
