This is definitely a nuanced topic involving the need for definitions. I probably should have already defined my own definitions before hand LOL
Disclaimer: these are my opinions and I am not a religious scholar. These definitions are my working definitions and or not necessarily correct
I see spirituality as a general belief in things beyond our knowledge, perhaps Supernatural. Spirituality can exist without religion. For example, you might walk out to a beautiful lake under the moon and feel as though there is some form of energy or presents around you, but it is hardly an organized dogmatic framework.
I Define religion as an organized set of practices and beliefs which are used to facilitate either the understanding of, and/or, the interaction with something spiritual, not necessarily a God but at least something to be worshipped. I don’t exclude them to Supernaturalality as there could be religions who worship nature itself.
To put it very simply, I see spirituality as the belief in something beyond our immediate material understanding while religion is the framework by which we interact with the spiritual, in a formal, reproducible manner.
I see gods as a central coalescence of some form of spirituality. They are a focal point often given anthropomorphic features and typically have some sense of agency, being anthropogenic in nature.
I would categorize both religion and spirituality as systems of belief, one a primitive varient while the other organized. I would categorize animism as a belief which could take the form of spirituality or religion, depending on how it is implemented. If you believe that the animals and nature are perhaps harbingers of Omens, this might be an example of spiritualism. If you kneel before a shrine to the bears of the forest and pray to them for a plentiful Harvest, this would be more of a religion.
While it may sound like my definition is more nuanced than substantial, consider that spiritualism rarely leads too ideology and fundamentalism, whereas religion most certainly does. It’s that sense of religious sectarianism, and if there is a God involved, divine inspired Authority/agency which provides people with the mechanism to do things they would otherwise consider immoral, and both feel moral doing it and be judged likewise.
