Are the ocean currents and climate zones of my world plausible?

So, I'm making my first stab at worldbuilding, and I got this idea for a largely water world with only a single continental landmass, a little smaller than Africa in terms of land area, roughly centered on the equator. So I followed Artifexian's video guides and tried mapping out prevailing winds, ocean currents and climate zones for my continent, but I have to admit I'm not sure on all of these. Do they look plausible at all, or does something badly need to change?

To clarify, this is for a planet that's otherwise basically Earth. The mountains encircling most of the continent's interior are supposed to be pretty old, and thus not very tall, though I honestly haven't given them much thought. Basically, I'd be fine with any combination of elevations if it can help preserve my climate zones.

EDIT: Thanks for all the great answers and suggestions. I did an updated version based on all the advice.
