No. What you are linking to is exactly what I was talking about, and you should carefully read what you are linking to: This only applies to some states. In the typically more conservative, right-wing southern ones, pupils with deficiencies in German are required to attend German lessons. In the typically more left-wing northern states, such requirements tend to be frowned upon, and even a voluntary offering of remedial German lessons is often not provided.

Also, the agency you are linking to is responsible for recent immigrants. That is relevant because some states offer German lessons only to refugees, asylum seekers, etc. But not to children born in Germany, sometimes even with citizenship, who nonetheless do not speak sufficient German because their parents don't. This group is a significant part of the problem.
