Does changing location using NordVPN reflect said location everywhere?

Silly question, but I’m a bit new to ExpressVPN and I was wondering; if I were to change my location/ip address using ExpressVPN does the VPN set that new location as my location/ip across the board? Like on all websites, forums, etc.?

Only when you visit them while connected to the VPN

Expessvpn changes your ip address, but apps that use location services can still see your location. There are apps that will spoof your location.
