Thor Love and Thunder does appear to present them as something unique and different. Aside from the fact that they have their own clubhouse, the Godkiller weapon seems to be very specifically designed for and intent upon killing them, so it must have some working definition - and there does appear to be some aspect of worship.
In Infinity War, the Children of Thanos - especially this guy - did seem to present his crusade as some form of divine judgement. I think it tips over from hero worship into actual worship.
