No, you don't get a deduction from the professional license. Both of the indie licenses allow you create, work on & release as many indie titles as you like (digitally).
The professionally license does come with the indie license, but the fundamental difference between indie & the professional license is that you can only use the professional license on a single title (game) that you want to publish. Both licenses are commercial, so don't worry about that. You only need a professional license if you have been commissioned (hired) by a third party (such as a publisher, company or individual) to develop a game for them &/or if you intend to release your game as a physical boxed copy in retail stores such as Game, Grainger Games, CEX, etc (listing some uk stores I can remember off the top of my head).
If you do decide that you eventually need a professional license or mobile license (which is also per title), then you can purchase one at a later date, as & when you need it, other than that the most you will need for testing & development is an indie single or indie multi license (if you are working with multiple developers on the same project in the same location, say a studio or your bedroom, or whatever).
