Most blind people are not 100% completely blind, but severely visually impaired.
Definitions vary somewhat by where you are, and some countries have subcategories that others don't. In the US for example, vision worse than 20/200 (in your best eye, wearing proper glasses if you need them) or a visual field of 20 degrees or less is considered legal blindness.
Roughly speaking, 20/20 vision means the ability to see with a normal amount of clarity. Someone with 20/200 vision, then, would be able to see at 20 feet away what a person with normal 20/20 vision would be able to see at 200 feet away.
Some legally blind people have enough vision they feel confident walking without a cane, or only use a cane in certain situations. Some may have disorders that significantly impact their ability to see in bright light or in dark conditions, so only use a cane sometimes. Someone with a restricted visual field might feel comfortable without a cane, or only use a cane sometimes.
Some might really need a cane, but just not be ready to use one yet.
If it would be rude to ask this guy questions about his vision highly depends on your relationship to him. If you're a friend, ask him if it's okay to ask some questions. If you're a stranger, it's probably rude.

I'm the same. No cane or dog but I'm almost totally blind. If we're born this way we learn to adapt.

Hey not a dumb question at all, asking questions is totally fine. If you know him a little bit and they are just not out of nowhere either way it’s fine, probably better if you know him a little bit. If he reacts badly and you have asked in a friendly and polite way then it is his problem his insecurities.
I am a mail and I enjoy it when people ask questions, I am brace the opportunity to spread information and hey I might make a new friend or two
