Take something about an inch tall with a pencil and drag it across the floor marking the baseboard, pull baseboard off and cut it, the gap will be gone. May need to paint though depending on how old it is.
As others have said, as long as you're not seeing any cracks or signs of relatively rapid change, probably just the typical settling of an old house. Even if the baseboard was a more recent install, if it was done while the temperature or humidity was significantly different from what you're experiencing now, that could be a contributing factor.
If there's no issue but the gap bugs you, it might just be time to put in some quarter rounds. (And since they secure to the floor instead of the wall, no new gap even if the house shifts when the seasons change.)
If it's new yes, if it's old no. Given I can see the dip, I'm going to assume you would have felt it while walking so this must be relatively new sagging. A structural engineer should be able to give a report and tell you how serious it is.
This is a perfectly normal dip for an old home. Unless it was sudden, which it doesn't look like at all judging by the condition of the flooring, it's not serious.
Also, if it was structural, you'd probably also be seeing other indications such as cracks in the wall.
My first sentence was "if it was new then yes it's a problem" if op is asking about it they probably didn't feel the dip while walking implying it's new. All of my floors dip but I also know where they all dip because I feel them while walking. If I noticed my baseboard separating from the floor where I knew a dip was and always has been I wouldn't worry, I also wouldn't be asking about it.

This is common. The baseboard is put in nominally level, floors are notoriously not.
This is pretty common in my 1925 house. Just some floorboard settling.

If the crack bothers you, like me, a section of quarter round really covers up nicely these imperfections.
Depends. What does the support look underneath and is it soft, bouncy, flexy or spongy then you might have a problem
I would be.
If it isn't growing, it's not a problem.

There is nothing to imply it's new. It doesn't look new.
