Wallet address rarely shared among multiple user though, unless you use custodial service.
It's not that rear if you think about it.
I think dkbit98 meant wallet addresses can be paid to by multiple users. Although not recommended, it's not uncommon to ask different people to pay to the same address. I even see it on Bitcointalk for raffles or paying back loans, I've seen Bitpay do it, and I've seen instant exchangers reuse addresses.
Yes, and I even know some cases with multiple members of one family are using one bitcoin address, or some company is using only one addresses for accepting payments or donations.
That means that Bitcoin address can be personal used by one human but it's not necessarily, similar like one family is using one IP address in the same home,
or how internet providers have shared IP's instead of more expensive static IP addresses.
