The profit was more like 10k because the hosts all convinced me each server could only handle 256 IP addresses.

And I shut it down because the support requests became unmanageable, there was rampant fraud, chargeback rates were through the roof. I had more important things to do / opportunities to focus on.

Is there an implication that the bills appoached $20k/month? Whether he owed $1/month or $20k/month, 20k/month is only being asserted as at least equal to the amount of his unspecified bills.

College bills i would guess

but $20k is like, a year's tuition at a University. Did parent also rent a mansion to live in while attending?

Depending on the university that might not cover a semester. Still, within 6 months of making money at that level, your post tax earnings are going to be enough for even the most expensive undergraduate programs

It also depends on when this was.

Or like a whole degree from bachelor to masters and a 15.000$ car (in Europe)

Good luck paying living expenses for years with only $5k in one of the many European countries that don't generally provide stipends for that. I'm a student in Switzerland where my university recommends more like $2,300 a month.

I know plenty of families living comfortably in Europe for <15k/year. Not Switzerland though.

But then afterwards he would barely make more than a barista

If he lived in California, he'd only be taking home 10K a month. Tuition, room and board at Stanford would take most of the rest.

"only" 10k a month

Tuition, room and board at stanford isn't $120k

It's around $80k, plus computer and travel
