No. You are not correct. Read their methodology
(http://www.securityspace.com/s_survey/faq.html?mondir=/200804&domdir=&domain=)
which I have copied and pasted below
We visit what we consider well-known sites. In our case, we define a
well-known site as a site that had a link to it from at least one other
site that we consider well-known. So, if we are visiting you, it means
we know about you through a link from another site.
If a site stops responding to our request for 3 consecutive months, we
automatically remove it from the survey. In this fashion, our list of
known servers remains up to date.
Because of this technique, we find that we actually only visit about 10%
of the web sites out on the web. This is because approximately 90% of
all web sites are "fringe" sites, such as domain squatters, personal web
sites, etc., that are considered unimportant by the rest of the web
community (because no-one considers them important enough to link to.)

Geez. What the heck is wrong with you people and your seriously bogus

Try a real recognized neutral tracking service like Netcraft

<Does anyone believe that they are biased and coking their data?>
March 2008 Percent April 2008 Percent Change
Apache 82,454,415 50.69% 83,554,638 50.42% -0.27
Microsoft 57,698,503 35.47% 58,547,355 35.33% -0.14
Google 9,012,004 5.54% 10,079,333 6.08% 0.54
lighttpd 1,552,650 0.95% 1,495,308 0.90% -0.05
Sun 546,581 0.34% 547,873 0.33% -0.01
As I understand it, Netcraft's results are based on web sites, or more
precisely, hostnames, rather than actual web servers. This introduces
a bias because some servers run a large number of low-volume (or zero
volume) web sites.

This gives 73% for Apache and 19% for Microsoft.
