Yes. Maa Kali is still very widely worshipped today. She has many hundreds of thousands of devotees. The only aspects of God that are not so widely worshipped in the present day are the Rigvedic deities, which are God in the form of fire (Agni), the sun (Surya), the dawn (Usha) and the weather, or master of the elements (Indra), including many others.
The elemental deities in Hinduism are now revered in a subtle sense and are mostly used for the worship of other deities like Lord Shiva, Lord Vishnu and His incarnations, the many forms of Devi (including Maa Kali), and many other relevant forms of God for this era.
I hope I’ve helped you!
Jai Maa Kali Ki!
