We recently purchased a resale house, which is about 25 years old. I just noticed there is a gap where the floor, wall and stair (leading to basement) meet. The gap seems pretty big (about 1 cm). This was not caught by the inspector.
Is this something to be concerned of or I can simply caulk it?

OK - based on picture at the bottom you need to:
That is the easy option and could look great for years.
The other option is buy trim/pine-board and cut out a triangle so that you form a rectangle where that wall is cracking. Based on the indention and cracking it looks like the wall above may be sitting on something less stable and moving - that triangle looks awfully out of place and I usually see that on wall over concrete.
Note that if this is moving around seasonally that much you may just need to cover the entire area with something more flexible - wainscoting, planks, etc.
