Without having more details, I generally wouldn't say one would feel Schadenfreude in your example.

Now, if your acquaintance is obnoxious or is putting everyone down for not being able to afford their dream vacations, then yes, Schadenfreude would apply.

In more general terms, you don't feel Schadenfreude whenever something bad happens to someone. There has to be a sense of "Well, that guy had it coming".
