Well, it's a non-commercial license. The $2000 limit is already kind of generous, especially since it's a profit limit and not a revenue limit.
Without having read the fineprint you could make a lot of revenue as long as you keep reinvesting the money into stuff related to your solidworks side-hustle (buying 3D printers, material, CNC machines, workstations, whatever).
It's available to people making less than $2k/yr from projects.
If you make more than $2k/yr, you need to pay standard prices, which start at $2.8k/yr.
