Great question!
There are a variety of ways for a speaker to give to deliver a presentation. While there are some caveats, generally a speaker will use their notes as little as possible or not at all.
An obvious exception is if the speaker is delivering a paper or other major written work. It would be almost impossible for a speaker to not read from the work.
To be clear: it is not bad for a speaker to have notes, but it is best when the speaker gives the audience as much eye contact as possible. Notes are best when they aren't full sentences, but key phrases so that the speaker can know where they are in their speech but not get tied down in exact wording. An audience wants to feel like the speaker is connecting to them, if the speaker is staring down at their notes the whole time this connection doesn't happen.
