That looks as expected to me. The Mark_engraver is on Staff level
and the Lyrics context goes above your Staff context, so the lyrics
get higher than the marks. Why would it look different?

I think you likely want to move the Mark_engraver to a kind
of MarkLine context instead. I was going to recommend moving
it to StaffGroup, but I found
https://gitlab.com/lilypond/lilypond/-/issues/6357

\version "2.23.10"

music = { a'1 ~ | a' }
text = \lyricmode {
  foo __

}
top = { s1 | \mark\default s1 }

\score {
  <<
    \new MarkLine \top
    \new Staff = "staff" <<
      \music
      \new NullVoice = "aligner" \music
    >>
    \new Lyrics \with {
      alignAboveContext = "staff"
    }
      \lyricsto "aligner" \text
  >>
  \layout {
    \context {
      \Score
      \remove Mark_engraver
      \remove Staff_collecting_engraver
      \accepts MarkLine
    }
    \context {
      \name MarkLine
      \type Engraver_group
      \consists Axis_group_engraver
      \consists Mark_engraver
      \override VerticalAxisGroup.staff-affinity = #DOWN
      \override VerticalAxisGroup.nonstaff-relatedstaff-spacing.padding 
= #0.5
      \override VerticalAxisGroup.nonstaff-nonstaff-spacing.padding = #0.5
    }
  }
}
