You don't need to spend much at all. Mora makes a great carving knife for around 15$
Not sure if it's the same in the US, you can spend way more money if you want just like any other hobby. But you really don't need to.
It was a bit more expensive in the US, here is a link

I've been using these for a long time and they are easy to sharpen and retain their sharpness well. Especially the laminated blades. They have both laminated and carbon steel blades.
most carvers I think have one of these https://www.amazon.com/Morakniv-Wood-Carving-120-Knife/dp/B09JJ8HRBH/ I've had one for over 30 years that the handle is worn to the shape of my hand.

These are small chisels. Used mainly for relief carving which is a hard thing for beginners. I'd suggest you get one of these https://www.amazon.com/Carving-Include-Whittling-Detail-Sharpener/dp/B0833NPKFH/ref=zg_bs_8090896011_23?_encoding=UTF8&psc=1&refRID=A1FYWGX11RQB3VWPHE11 sets. They're relatively cheap ( around 15-35$) , and they're pretty good for beginners.
There ain't no point in spending money on professional tools yet since you're new. So grab one of these. These are used for wood carving. So anything from figurines to spoon ( which is why I bought them) etc.
Go slow, practice , and remember to have fun. You don't necessarily have to follow any guides. Once you learn a piece like a spoon, then you can do it by yourself and add your own twist on it. Good luck :)
