It looks like there’s still some troubleshooting happening in your other thread that’s likely relevant to your question here.
One important thing to remember, like spikey said, use tutorials and their explicit values as guidelines. Generally they shouldn’t be that far off but it’s common for them to differ slightly between Blender versions. Treating them like guides instead of objective rules will teach you to lean on their function more than their values. Which is a far more robust and applicable understanding.
