Pre-installed Plugins

When I downloaded WP, WooCommerce and the Kadence theme I have a list of installed plugins. Quite a few have 2 versions, one plain and one pro. Are the pro versions free or at some point are they going to run out of a free trial and start requesting payment. I don’t want to get used to using something and then have it pulled out from under me later on. I’d rather deactivate them now and get used to the free version and then decide which ones I need more from and upgrade then.
