To clarify, OP appears to be referring to the fact that more than 0.3% of all bitcoins are being held in P2TR addresses now.

Meanwhile:

• 23.2% of all UTXOs are P2TR outputs (see e.g. https://dune.com/murchandamus/bitcoins-utxo-set): https://i.stack.imgur.com/zvQIV.png
• In the past week 30% of all outputs were P2TR (via https://transactionfee.info/charts/output-type-distribution-count/): https://i.stack.imgur.com/IKYR7.png
• And about 38.5% of all transactions in the last week had at least one P2TR input (via https://transactionfee.info/charts/transactions-spending-taproot/):
