Not necessarily: a straightforward steelmanning would re-define "anything in this world" as "anything in this world I can get by paying an appropriate price (not necessarily in money)".

Even with that restriction, the quote would still be false. In terms of things priced financially, there are lots of objects which cost more than many peoples' lifetime earnings (and good luck trying to raise those earnings by a large multiplier). In terms of things priced in terms of time or effort - there are limits on those too. If, for instance, a nonagenarian enrolled in a Ph.D. program which typically took a decade to complete - they might earn their degree, but the odds are against it.
