I'm not seeing any of this, and I've have been using the same email address that forwards to gmail for decades at this point, and it's in every major email data breach.

I get, maybe, one actual spam email per year through gmail's spam filters.

I get more actual spam at my work email, which is not hosted by gmail, even though the email volume of emails sent from outside of my employer's network is orders of magnitude smaller than my personal email volume.
