With the right ski instructor you might surprise yourself. I took skiing up in my late 40s, husband was in early 50s. The modern short fat skis are surprisingly stable and I found it a lot easier to do than cross country (I fall down a LOT in cross country and gave it up). Boot fit is the big deal because if it's too loose you fall a lot, too stiff and it's the same thing. But if you have a squirrelly ankle that likes to turn on you and make you fall (which I do), those downhill boots lock it in and you don't even wobble.

But it does take the right ski instructor for sure....
