Summary: I opened up my timing cover and saw the camshaft timing belt marks won't align at TDC but the truck drives "fine". No one has tinkered with my timing belt or components since I have owned it (15k miles). I want to replace timing belt and water pump.

------
To begin, is how my engine sounded right before I unhooked the battery and began removing various components to access my timing cover. Everything starts. It drives. It doesn't sounds awesome, but it runs and gets me to work.

I'm replacing my timing belt, water pump, etc. preemptively as the engine is sounding funky all of a sudden (as of last month). It's got 210,000 miles on it, and it's evident that the last few owners have not taken good care of this truck. The timing belt/water pump components are the most recent things I am going to replace, but I am reluctant to go any further with the repair due to the following:

All my manuals state that before I take the timing belt off, I have to align everything top dead center and line up the timing marks accordingly. The problem is, the marks just aren't lining up...at all. To repeat--I haven't touched anything; the timing belt nor any timing components. I have not adjusted any tensioners and the belt is taught. This is what everything looks like right now (see photos below)

No matter how many times I turn the Crankshaft by hand with my socket and ratchet--the Camshaft marks never sync up with the oil pump or crankshaft. I've turned the crankshaft around and around and it never lines up with the other two timing mark sets simultaneously. What gives? The manual alleges these marks are all supposed to be aligned before taking the old belt off, but if they aren't lining up, how to I move forward with this project especially since the engine, for all intents and purposes, seems to be running just fine?

First picture: Crankshaft is lined up Top Dead Center
Second picture: ...Oil Pump Sprocket marks are [mostly] lined up...
Third picture: Camshaft Pulley
Fourth picture: Camshaft Pulley with the timing cover off for a better view of how. far. off. the camshaft timing marks are...

So what gives? Why is my truck driving and operable if the timing is this far off? What am I missing? Last I checked, my Ranger was not magical. My crankshaft pulley bolt & pulley are still intact, have not been removed nor loosened. My #1 cylinder spark plugs are both out. Truck is in park. (Should it be in neutral?)

I have spent the last several hours on google and I cannot find any solutions. It seems like everyone's timing belts line up before removal--so this has got to be operator error, right? Or is this normal and I just install the new belt using/keeping the janky positioning of my camshaft where it is? I'm really keen on doing this repair myself, but if I have to reassemble everything and take it to a pro I will...albeit begrudgingly.
