They will say lost bitcoin is estimated to be...

[Gladitorcomeback]

Yes it is true. This case shows that we should be very careful before labelling any Bitcoin supply as lost just because we have not seen any movement to this Wallet for years. In the case of  Clifton Collins we understand that the inaccessible Wallet can suddenly become active again any time. As far as seed phrase or wallet is there the coins can be transferred any time.

There are many wallets where no movement seen for more than 10 years. There is possibility that many wallets owner passed away ot have no access to wallet because of forgetting keys or something else but there is still chance for some wallets to be active again as some wallet owner want to holds for long term, found access to wallet etc. Bitcoin has always surprised the world. It's safe to say that these BTC are dormant , not yet lost.

The chance is never a zero, it's some number, albeit the one with lots of zeroes in it

Although coin not moved since 2019 may be seen as not lost but how about those not active since 10 or more years ago.

2019 to 2026 is quite a long period of time for a bitcoin holder and in as much as the coins to the particular are not accumulating up with new coins it easy to assume that either the keys to the wallet may have being lost or the owner may have passed on. Now imagine over 10 years ago, a wallet with dormant bitcoin for that lengthy years, it's only when it's moved we can be certain of a non loss just as this occurrence in the OP.
