Congratulations on getting your hunting license! The most important thing at the beginning is really the safety gear - you can't cut corners there. A good high-visibility vest in bright colors is mandatory, just like a reliable weapon and the knowledge of how to use it properly (your course should have taught you that). Otherwise, at the start normal, weather-resistant clothing in neutral colors is completely fine - camouflage patterns aren't necessary and cost a fortune.
For everything else, you can improvise at first. A regular sturdy backpack works just as well as one with a "hunting" label, a basic binocular of medium quality is totally sufficient (the premium gear is nice-to-have, not need-to-have), and you can buy specialized hunting boots later when you realize you actually need them. What's more important is talking with the more experienced hunters in your area - they can often recommend used gear or pass things along to you. Find yourself a mentor who can show you what's really worth the investment.
Start small, see how you grow into the hobby, and then buy specific things once you figure out what you're actually missing. That way you'll also avoid wasting money on stuff you don't need and you'll quickly find out what you personally don't want to do without.
