Absolutely, and not just with sponsorships and advertising, either. You can generate an income by selling your own products, recommending and promoting other people's products (affiliate marketing), selling event tickets, and even tools like Patreon make it simple and fun for your audience to support you over time and help you earn money from your podcast. If you were not thinking about making money from your podcast, you should! It can be done in a graceful way where everyone can win, and you can supplement what you are creating for others and keep going long and strong!
