Legacy 15-pin game ports are analog.
I take it you have the classic Gravis joystick?

That one is analog.
Digital joysticks usually 'click' when you push them in a certain direction, because they use micro-switches. Analog PC joystics are proportional, and don't make a sound.

Thanks for this info. I have the same Gravis as shown in the image.

Depends... I had a digital style with gameport connector back in 1995. Wich I used for shooters and platform games.
Then at the same time, I had an analog Logitech Wingman Extreme for flightsims. This was gameport connector too.

The gameport itself is analog by definition, digital gameports kindda "cheated", but that did have its issues. Anyway... if it has a stick and doesn't click, it should be analog.

Yes, PC joystick axes are analog (just potentiometers) and buttons are digital (on/off).

So called digital joysticks like Logitech Wingman Extreme Digital, are still analog joysticks with potentiometers, but they have a special mode where a microcontroller inside the joystick is the one that converts the analog potentiometer value into digital value and this is transferred digitally through the digital button pins.

Joystick can also use membrane contacts and these don't click and yet they are still digital. Only better joysticks had microswitches that make the distinguish clicking sound.

I remember one PC joystick that had potentiometers (some dials) around the stick to calibrate/center the stick. So this kind (with dials) are surely analog.

Like this one:
