Not necessarily. Moulds across that sort of breadth would either be a MAJOR leak on the outside cladding, or it's internal and condensation based

Yeah condensation every morning after I wake up.

I believe it's just condensation. I'm using a window vac to remove the moisture at the moment but want to redo the paint to get rid of the mould.

Bleach doesn’t kill the roots of mold, only the surface.
Vinegar or a mold-specific treatment would kill the mold thoroughly, but until you find the source of the moisture (eg is a sprinkler pointed at that wall?? broken gutter? plumbing issue??) you’re masking the symptoms, not fixing the cause.

This just says "detergent"

I included the EPA link because it specifically mentions not to use bleach, but instead a mold-killing detergent or agent, and also mentions that cleanup isn’t enough: the underlying cause needs to be addressed.
Use of white cleaning grade vinegar as an agent which kills many types of mold is covered here, if that’s more useful to you:

I believe it's just the amount of condensation it gets. I have a dehumidifier on 24/7 and I still have to mop the walls every morning.

I would take off that baseboard and cut out some of that Sheetrock to investigate. That window is probably leaking.

At a minimum you need to deal with the water, remove the damaged boards, and kill and clean the remaining material.

Do you have working trickle vents on those windows? It can be just condensation. I had no issues in my house until I sealed up gaps around old windows. Turns out the gaps were incidentally providing air flow. Got mould inside of 3 weeks.

No and it is condensation based. I have a window vac that takes care of the water to deal with it.

Yeah but that's not stopping the condensation in the first place. You see the condensation on the windows because glass isn't porous. Your walls will be soaking it up, and it's harder to see.
Clean it off with vinegar/bleach/mould spray (mould spray is usually just diluted bleach), crack a window a fraction, and turn the heat up. A dehumidifier will help in the first few days or so to help dry it out - but you have a wider problem. I know because I have the exact same problem as I've said with my bay window. The gaps around the old seals were acting as trickle vents and I got mould the moment I sealed them up.
It's the hardest thing to do in a house in the winter - keep it warm but also provide enough airflow

When I built my house it was so air tight that the city made me install air ports and an exhaust fan that runs about 3 hours a day to prevent build up of humidity and mold. Might be what you need to do....

Straight bleach should do it. It’s just mold after all. Try and keep the area dry. Or just hit it with a little bleach every now and then.

that dehumidifier is weak sauce, a proper one is rated around 300 watts and weighs 20 pounds, if relative humidity is above 60% inside you're gonna need at least one of those

You’re getting water in behind that drywall somehow. You’ll need to find where it’s coming in and seal that first.
