Does the TRASH folder go into Time Machine?

Question

So i've been able to backup time machine the first few times, but after that it says "the backup is too large for the backup volume". I have one folder "excluded" where i add and delete very large files (sometimes up to GBs).
I'm wondering if i delete these huge files and they go to the TRASH and then I immediately empty the trash...Do they get included into my time machine backup? Could that be what maybe causing the large size error? If so, where is the trash folder so that i can exclude it? Thanks.
