Every particle type has its own field, but the OP article is counting a single particle type multiple times based on properties like spin and polarization. At one point the article reaches the number 118. That corresponds directly to 37 quantum fields once you take the "double counting" into account.

Where are you getting 37? The standard model has 17 fields.

If you pick and choose which properties to select as unique fields, maybe you can get the number 37, but at that point why not 118 fields?
