Yeah... I understood the ask ;)

In your example the tab is strictly finger-picking over chords since that's how the song goes but some tabs are lead guitar tabs which might be sliding from the 15th fret to the 3rd fret or other things that are not strictly picked from a chord shape. They might still be "from a chord" or "played over a chord" but when you play the tab you may or may not be using that shape at that position. It's still good to know what's the context so definitely having the chord is useful.

If I'm playing a song with a clear picking pattern over chords I might just learn the chords and strum them first and then learn the pattern or often the patterns are just standard and all you need is the chord chart.

I've definitely seen tabs with the chords on top, in Ultimate Guitar it depends on whoever transcribed it, random e.g.: https://tabs.ultimate-guitar.com/tab/misc-traditional/greens...
