How many Tezos are left?

Could you please elaborate on the matter of Tezos' remaining supply? I'm curious to know, given the dynamics of the cryptocurrency market, how many Tezos tokens are still available for trading or staking? Has there been a significant change in the total supply due to burns, staking rewards, or any other mechanisms inherent to the Tezos blockchain? Additionally, is there a way to track the real-time supply of Tezos to stay updated on its availability? Your insights would be greatly appreciated.
