How many skill proficiencies do I choose as a Triton Bard?

I’m extremely new to dnd, and have little understanding on the game so far.

Right now, I’m creating my character, a Triton bard with a folk hero background, and I’m having trouble selecting proficiencies.

I was told that bards have no predetermined skill list to choose from, but that seems weird. I also have absolutely no idea how many skills to choose.
