No. That is not a logical consequence of what I said.
The Catholic Church understands Original Sin to consist in:
The absence of sanctifying grace (charity) at conception;
The absence of “felt grace” in the developing child; i.e., no experience of God as present;
The resulting distortion of the consciousness of the child; it is turned in on itself; it experiences itself as the “center of the universe.” As a consequence, the entire psychic structure, all the faculties, are distorted in such a way that makes charity seem and feel “unnatural” and selfishness and self-seeking feel “natural.”
When the age of reason is reached, the consequence is deliberate sin.
The only “nature” a human being has or inherits is his human nature. Sin is a privation or distortion of what is good, but it is not itself a positive reality. There is no “sin nature” existing as an actual “thing.”
As you can see, there was no warrant for your statement that the Catholic Church does not teach about Original Sin.
Without His grace on our lives, we wouldn't be drawing our next breath. We'd be burning in hell where we ALL belong unless we've been born again.

human nature = sin nature
Nobody is inherently good until corrupted by sin.
We are sinners by birth into the human race.
We sin because we're sinners, we're not sinners because we sin.
