Licence Question: Twitch and Saas Products

Hi, I have two questions about the licence for products as Envato Elements user.

  1. Can I use the items like themes also for products, which my users have to pay for. I mean saas products, where people pay, login and use the service? At themeforest it seems they need the extended licence. But here I only pay 15 Dollar an get a version where I can use it for the paid product? Is that right?

  2. Can I use stock images, videos and sounds for Youtube videos and twitch streams?
