The issue with your argumentation about Hamas making stuff up (which all sides do during war), is that in this case the humanitarian crisis and famine being reported is not a hoax by Hamas, it's actually reportered by several Western Countries including allies of Israel who are urging it to stop its blockade and stop shooting at Palestinians near distribution points, as well as dozens and dozens of Western reporters and Western NGO's also reporting it all.
I get it, you want to not think black and white and take things with a pinch of salt, but here you're being overly skeptical to the point that hearing you sounds like you're describing a conspiracy theory.
It's not that complicated out of logic to understand how people are starving when they run out of food and there's a blockage with most food aids stopped from entering, while there are on-the-ground reporters from our countries showing it all on camera.
I'm not sure what more it would take to make you realise what's happening, other than perhaps physically taking you there for a walk around and visiting those people starving to death, hospitals, etc. And even then, you'd probably say it's all fabricated and it's fake humans dying, it's all orchestrated with AI and special effects. Get a grip.
