In opentelemetry, if I use `TraceIdRatioBasedSampler`, will it sample all kinds of requests in the same way?

will it randomly pick 90% of all requests?
or it will send 100% of error requests and 90% of random successful requests?

I believe its all requests, we had to run an OTEL collector with a tail based sampler to get all error traces
