Wallet Recovery – I lost my network connection in 2009 and can I reactivate it years later in 2021?

I still live at the same address as I did 15 years ago in 2009. I hit the generate button in Bitcoin Qt as instructed in the invitation email and actively started mining Bitcoin. I didn’t log in because I didn’t need to at the time. Later, when I connect another computer, but in the same building in 2021, I requested network replication and installed the wallet.dat file. A wallet.dat file created in 2021 may be the same as a wallet.dat from 2009 if the network becomes active again after 15 days. age?
