Those are not related:

Every time you receive a payment, you get a new UTXO regardless of the address you gave to receive the payment
Every time you pay you could get a new UTXO (your change, if any) regardless of the address you use to receive the change

Re-using addresses does not reduce (or increment) the number of UTXOs

i have to admit, there's always something extra to confuse me about utxos, thanks for explaining though.

so far, my utxo consolidation has been sending to a new address , i only did it once.

as an example, say i i do my monthly dca of 100k sats

over 12 months i have 12 addresses in my ledger that each have 100k sats

my understanding is that i can make a new address, send each of those 12 balances there and i have now consolidated.

is this new recipient address now consolidated, or did i just make ton more utxo addresses?

You don't consolidate addresses, you consolidate UTXOs.

Your assumption is correct, you get 1 new UTXO every month, and at the end of the year you consolidate 12 UTXOs into 1.

The above is true if you use 13 different addresses, the same address for every UTXO or even a mix: it doesn't matter.
