The STM32F302CBT6 pins in the schematic you shared here do not match, can you help?

It's not a "mistake" per se. It's just that I started out with the STM32F373 in mind, because it has better ADCs, but it was hard to source. So I decided on the (somewhat compatible) STM32F302, which is more widespread.
The symbol is from the STM32F373 and mostly matches the STM32F302, but some pins are connected such that both MCUs could potentially be used.

Do you suggest I do it by pin names and not by pin numbers?

Do what exactly? For the pins that we are using, both pin names and pin numbers (should) match your correct symbol.

I can merge it into your project if you check when I'm done

Updated Schematic I hope there is no mistake, if the general schematic is correct, I made some changes that will reduce the price, I wanted to make it easier for amateur friends.

Should be fine, as said the pins we are using should have the same pin name and number as you have now. Or did you see any deviation?

Yeah, but we are not using those here

Then there seems to be no problem, but could you please take a quick look at it?
