Unfortunately this is true only on paper. I grew up in (Indian) Punjab, the heartland of Sikhism and a Sikh-majority region. In practice Sikhs participate as fully in the caste system as Hindus.
Matrimonial advertisements for arranged marriages in newspapers are segregated by religion and caste, and that's true in Sikhism as well. See https://www.tribuneindia.com/classified/grommswanted . Notice almost all the Sikh listings include caste names as well (Jat Sikh, Gursikh, Khatri, Ramdasia, etc).
Mazhabi Sikhs (https://en.wikipedia.org/wiki/Mazhabi_Sikh) who are from 'untouchable' Hindu backgrounds are still discriminated against. They marry within their own communities. I've known 'high caste' Sikh parents to reject a groom from a Mazhabi background even when the groom was a high-ranking government officer with a prestigious job (as in the kind where he always has a police cordon around him).
Punjabi comedy openly includes casteist slurs against mercantile Sikh castes. I could cite some but they are in Punjabi.
There's just so much against evidence against Sikhs not embracing equality in real life that I don't know where to start talking about it. They are simply no better and no worse than other Indians in this regard.
