Some classes will have their own mechanics switch this up a bit, but ultimately you have a set number of spells you can cast per day - not per battle - and you'll need to camp to replenish them. Depending on your class, you may also need to plan-out which spells you expect to use each time you camp, e.g. this time I'm resting, I'll memorize 3x magic missile, 1x charm, 1x fireball, etc.
There are a bunch of ways to kind of get around it, and sorcerer doesn't have to plan which spells to use each sleep (but does on level-up), but at the end of the day that's the combat mechanic that's most different from mainstream, mana-based RPGs IMO.
Addressing the bold part, not true for BG3 since it’s based on 5th edition rule set. In D&D and Pathfinder they call the method where Wizards and some other spellcasters need to prepare a number of usages of specific spells “Vancian Spellcasting” (named after an author that heavily inspired Gary Gygax). 5th edition got rid of Vancian Spellcasting, which may or may not be a big reason Spellcasting classes blow past martial characters at higher levels as their utility skyrockets.
