Just to add a little light on this, the Roll20 Marketplace supports giving a PDF with the product, and many products have the PDF. If the product does include a PDF then you can download it from the Marketplace page after purchasing the product. I recommend surf back to the Marketplace pages of products you have purchased and double-check again to see if it has a PDF. It's really up to the Publisher of the module or game system, to include the PDF. It's their choice. Unfortunately the biggest game right now, D&D 5E, is one that doesn't give the PDF, because of the decision of their publisher WoTC. Are you suggesting for WoTC to include the PDF's with the D&D 5E or 5E 2024 products, or Roll20 to try to get WoTC to allow that? Or do you play a different system/module and noticed it's missing PDF?
