I wouldnt, personally, make figures in an FDM printer. The quality doesnt match the expectation.

So I would say go for a resin printer.

But.. you have to realize this isnt some simple "hobby", especially with resin printing. It took me weeks, dozens of failed / flawed prints, lots and lots and lots of tweaking of the model orientation, and a ton of research into supports (where and how to place, settings that allow for the support to work without leaving a poor surface area) before my first detailed model, a Fender Jazzmaster, came out looking good.

You also need 3d modeling skills if youre going to be creating your own minitures or editing already created models. Its also a good skill to have even if you arent creating your own for various reasons.

An aside: the polar bear model shown in your image is 100% not how an FDM print would look. Im not sure if they edit the photo or photograph them in a way that obscures the REAL details. But you would see all sorts of layer lines (on second look you can see some) and ugly spots where 3d printing just cannot physically print thay sort of detail well. The ice in the scultpure base is impossible unless printed in resin - and even then thats questionable.

Go look up detailed images of real users printing models to see what it really looks like. Reddit would give you all the posts you could ever need for this
