For sculpting I consider mouse and tablet interchangeable both have advantages and disadvantages there.
Tablets have better long stroke precision and pressure sensitivity going for it, mouse has better pixel accurate precision while dragging things around with grab tools.
Grab tools is my preffered way of shaping and manipulating surfaces so you tell me to sculpt with a mouse only I don't feel limited as it'd be my mainstay anyways.
for modelling I consider mouse extremely advantageous, I've never had the thought occur in my head to use the tablet for modelling (I'm a max guy).
Only place I use tablets exclusively is if I'm sitting down to draw or doing digital painting type tasks, day to day image editing of textures and photobashing etc I
typically end up using mouse only because I'm too lazy to pick up the tablet even if it would be better for certain manipulations.
Pic related is something I posted here few years ago when I was trying out blenders sculpting tools away from my may comp where I didn't have a tablet on hand, so mouse only.
Digital artists painted using shitty ball mouses for decades before tablets was a widespread thing and did amazing work, it's perfectly possible to become proficient enough to even draw and write clean handwriting dragging a mouse. If a mouse is all you have it's a perfectly viable tool anon. Lot of people do prefer tablets ofc but they're not a requirement.
