Should I invest in washes as a beginner? - eviltoast

So I’m getting ready to dive into the world of finally painting my Star Wars Legion minis. I’m planning on getting an Army Painter speedpaint 2.0 set to start. Should I also buy the wash set? I’m not sure if it would improve my results as a beginner, though I imagine I will want them if I keep up with painting. I’m intending to start by getting this Army Painter’s stuff:

Speedpaint most wanted 2.0 set

Most wanted brush set

Matte white primer

Matte varnish
