Does the Bech32 address format decrease Bitcoin's possible address count? I have wondered how many Bitcoin addresses are possible. When looking around, I stumbled upon this thread on BitcoinTalk:

There are exactly 2^160 possible addresses as long as we keep using
RIPE-MD160.
2^160 is
1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976.

Then I wondered if there are less possible addresses with the Bech32-format, specified by BIP 0173.
Besides, you cannot use uppercase format of characters in your computation, and some numbers as letters, such as i/1 and o/0 characters/numbers are excluded in Bech32 format.
Should that not decrease the possible amount of Bitcoin addresses dramatically, and decrease the security of Bitcoin?
So, I would like to know how many possible Bitcoin addresses there are with Bech32 format. How could I calculate it? What will the total number (plain long number, not the squared one, I'm not good in math) of possibilities be with the restrictions of Bech32 then?
Keep in mind that both types of addresses, assuming we are comparing P2PKH with P2WPKH addresses, are just encoding the hash of a public key. The hash used in both address types is a RIPEMD-160(SHA-256(public key)), so regardless of the encoding, the number of possible valid addresses remains the same. Each address format is simply encoded with a different checksum system, different version system, and different characters. But neither address format is actually ever used within bitcoin transactions themselves, they both just get &quot;unwrapped&quot; when given to a wallet.
