I think the op wasn't looking at the present price of bitcoin, before asking the question. I believe that he is looking at the future price of bitcoin. A future where the bitcoin price might have skyrocketed to a price above $1m and beyond. To me it all depends on the price that bitcoin will be before my children takeover from me. We never can tell what price that bitcoin will get to. Bitcoin could get to 1 billion dollars in the future, you never can tell. If it does that, it simply mean that 1 bitcoin can make a generational wealth.
As far as I can understand, that's what op wanted which is to know if having 1 bitcoin can make a generational wealth. I'd say the same. Who knows that bitcoin's price would reach more than the price of BTC right now in the future. Even this time, no one even expected to reach new ATH. I didn't even expected that btc price even reach its price right now when I remember btc price before is around 2-5k dollars when I just know about bitcoin a few years back.
