I'm not saying I can instantly program at expert level in any language I've never heard of. But yes, I can read most programming languages even without ever having seen them. Take LUA. I had never used LUA and when I started out I was reading code examples and writing LUA code without first "learning" it at all. I just went and did it. Did I probably do some "stupid things" that an expert would do differently and/or fast? Of course. But I got stuff done and learned as I went along. Same when we introduced Kotlin for example. I was instantly productive but someone using Kotlin for a longer time (such as today's me) would "cringe" at how I was writing Kotlin as if it was Java.
Notable exceptions would be languages that have such a weird syntax as Brainfuck ;)
SQL is a great example. I have not been using SQL directly for quite a long time now. But about 20 years ago my bread and butter was SQL and I was writing stored procedures every single working day and I was not writing any Java at that point in time but was using two other languages other than SQL on a daily basis as well (Perl and Bash).
