Really I started traditionally, but I wasn't able to upload anything due to having no decent scanner. Really just old printer paper, number 2 pencils and maybe if I'm feeling fancy, pencil crayons are appropriate enough to just start with and they cost absolutely nothing. That's the advantage, low cost of entry, and easier to see the full picture.
For digital, you can upload you drawings to social media much easier without a scanner and you get to learn alot of difficult to grip with aspects to digital art early. The problem is the cost is a lot higher. My digital tablet is a cheap Huion 420, so nothing fancy here. And yes medi Bang is an excellent starter program, free and perfect for comic making. There's also fire alpaca and krita. The issue is when you first learn digital art, it gets tempting to use ALL the effects and texture available, without any understanding. That's fine it helps you learn, but just know that looking back at your old art would be an eyesore tour.
Another thing, since you just starting out, you will rapidly improve especially if your doing a comic. So a page 12 would look vastly improved from a page 1, so just make a short comic to begin and finish and not worry too much about how different the 1st and last page looks, its normal. There's alot of youtube videos online to help you with certain art programs so its a good idea to watch them, probably even when your drawing. I find them relaxing.
