Racers do need to be quite strong, but in other words only "strong enough." There are other sports that are much more strength-dependent. Using BMX racing as an example, you can look at someone's weightroom numbers and know whether they have, at present, what it takes to be elite in that sport. For ski racing, you can't do that.
And again, that is ski racing, which is different from recreational skiing. Different skis, different number of runs, different forces, and for that matter being able to ski that way while not violating the Code.
Moreover, as racers have been studied over the years, there's been a bit of an evolution where racers have become actually somewhat less strong in weightroom terms, and more aerobically fit. In terms of causes, some of that is probably social as more have emulated the successful teams, some is probably due to people learning to better utilize modern equipment which rewards skill more than strength, and some is simply due to better sports science.
As a matter of analysis, the difference between e.g. ski racing and BMX also makes sense, because the mechanics of the start for BMX give such a benefit to those who can really crank for a few seconds. Whereas, for ski racing, that is much less the case. Again, looking at recreational skiing, there are even fewer moments where raw power is really rewarded.
That shouldn't be interpreted as saying there are no strength demands in recreational skiing. But, many training activities produce good amounts of the needed strength.
