user533: I'd like to determine the number of wallet holders for (example)

Lobster holders
ClayNation owners

How can I query this with a full node?

user1074: You would need db-sync to get that sort of data. https://github.com/input-output-hk/cardano-db-sync
You can use existing solutions like Koios (https://api.koios.rest/#overview).
Example for Lobster token:
curl -X GET "https://api.koios.rest/api/v0/asset_txs?_asset_policy=8654e8b350e298c80d2451beb5ed80fc9eee9f38ce6b039fb8706bc3&_asset_name=4c4f4253544552" 

Response:
[
  {
    "policy_id": "8654e8b350e298c80d2451beb5ed80fc9eee9f38ce6b039fb8706bc3",
    "asset_name": "4c4f4253544552",
    "total_transactions": 340660,
    "staked_wallets": 2433,
    "unstaked_addresses": 9
  }
