The [TraceIDRatioBased sampler](https://github.com/open-telemetry/opentelemetry-ruby/blob/1933d4c18e5f5e45c53fa9e902e58aa91e85cc38/sdk/lib/opentelemetry/sdk/trace/samplers/trace_id_ratio_based.rb) in the `opentelemetry-sdk` gem is different from [the new, Probability Sampler algorithm](https://opentelemetry.io/docs/specs/otel/trace/sdk/#probabilitysampler). Eventually, we may need to re-implement the TraceIDRatioBased sampler in our agent, or add a separate probability sampler.
