Why does linux mint warn that disk space is low?

Question

linux

A 500 GB disk is divided into two parts
1. 100 GB - mount point "/"
2. Everything else with a mount point on "/ home"

Recently, a warning has begun to appear that there is not enough space on "/".
As far as I understand, this is due to the fact that "/home" is taken into account when calculating the space for "/"

This warning infuriates a little. Can something be done about this?

Answer 1

Would they show something,
df -h
mount -a
