so i've just been wondering. Can tone deaf people hear intervals or no? I really don't know much about tone deafness and i was just wondering if you guys could give me information.
No. Tone deafness is the inability to tell the difference between different pitches.

"To know the truth of history is to realize its ultimate myth and its inevitable ambiguity." Everything is made up and the facts don't matter.

It depends on how tone deaf a person is. Its kinda like vision, where some people can see perfectly, some can see stuff but not tell what it is, and some people are blind. Some may hear intervals but not be able to reproduce them, some may not hear intervals, and some may be able to hear intervals a little bit, and be really terrible singers.
