For these actions, Stamina and usually tools are required, for crafting you also need the corresponding components. There is a chance of failure that depends on craft difficulty (indicated for the selected recipe and taking in consideration all bonuses and penalties of the villager). In some cases when you fail, you might lose some or all components when crafting fails (they always lost for potions and food).
