Actually make sense for Forgotten Realms settings. Almost everyone in Toril quite faithful at least to one god. Usually several.
It's how Ao created this cosmology specifically. Even unlike to Greyhawk (which is generally very similar to Forgotten Realms... or, rather vice-versa), mortals supposed to be faithful, and gods supposed to indirectly been involved in mortal's life. To the point where there is very harsh punishment in afterlife for faithless mortals, and sever punishment for gods who doesn't do their duty well enough. More explained in Time of Troubles on that topic (which is actually directly related to original Baldur's Gate trilogy, as well as partially to BG3).
Not everyone of course spends lots of time on praying, going on pilgrimage and other services to god(s). But usually everyone now and then spends a minute or two on silent pray to one of the gods, depending on the situation.

As examples:
You are about to spend your evening gambling - you generally would either give short pray to Tymora for better luck. Or at least to Beshaba to avoid really bad luck (but generally not to both, as both goddesses tend to punish you for that).
You about to go on sea voyage - you might want to consider giving prayer to Umberlee. Even if you are a good-aligned character yourself.
Even goddess like Shar. What BG3 tells about her is true. She is quite dark and evil goddess. And open religion to her is banned in most places. Common folks however generally doesn't know her fully. And if someone at loss or just overall experiencing dark period in their life - it is not uncommon to give quiet prayer to Shar, asking her to alleviate at least some of it.
