measure 10 and 19 shows the same description even notes are different, why?

Fm7 = F, Ab, C, Eb.

In measure 10, this is a common jazz voicing. The 5th is the least important chord member because it is naturally produced as an overtone from the root, F. So here you have 1, 3, 7.

In measure 19, this is known as a rootless voicing. You see C, Eb and Ab, or, 5, 7, 3. It's probably like this for ease of hand position. It's the same notes without the F, and the bass is playing the F, so it's not always necessary.

Something to remember is that the 7th chord, in its most basic usage, is a four note chord. In the two measures, you have only three notes of the Fm7 actually voiced. So the fourth member of the chord is implied or covered by something in the accompaniment. Fm7 is an F minor with the 7th added > (F, Ab, C) + Eb. In the two measures you have three of these four actually played, but a different member of the Fm7 is left out - the C in measure 10 and the F in measure 19.

Also, measure 10 is in Root position and measure 19 is in 2nd Inversion. They look different, but have the same soul, if you will.

Wau, thank you, I have a lot to learn though

Yes John, in the second example, the bass is covering the F.

However in the first example, it's possible that no other instruments are playing C. It's the least important chord member because it's a naturally produced overtone. Also, it doesn't provide any harmonic information that differs this harmony from Fmajor7 or F7 - they all have a C.

That's what I meant by implied. It's like your ears hear it whether it's there or not.

as a beginner I am still confused, honestly I would be less confused if I dont have those letters bellow. For example why note E has b symbol twice?

another example apart from that, again doubling b symbol

Cm7 is perfect example why I am strugling btw another b symbol twice but only for Cm7 (next to clef) not for Abmaj7 where it is more useful (if any)

my brain hurts hope you know that sketch from Monty Python, answer to my question, because

Fm7 = F Ab C Eb

but also
Fm7 = Ab C Eb F
Fm7 = C Eb F Ab
Fm7 = Eb F Ab C

and sometimes there is least important chord member, as a result we can have
Fm7 = F Ab Eb
or member covered by something in the accompaniment, as a result we can have
Fm7 = C Eb Ab

are my assumptions right?
