In fact, playing the violin or cello first depends on talent and has no direct relationship with gender. The fact is that female performers were banned in Western orchestras in the past, not because of gender discrimination, but because of work convenience. The reason is that the participation of women in an orchestra originally dominated by men will distract the male performers. When men and women work together, they will have such needs and problems (which may include jealousy because of women), and in the symphony orchestra Performance requires a high degree of concentration on the music and a high degree of unified expression of musical inspiration. Second, there are indeed differences in the understanding of music between men and women, and sometimes they are quite large. This may be why the world's greatest and most accomplished musicians are all men, and virtuoso players are no exception. For example, I can guess 90% whether the performer is male or female without watching the video.
But today, it is an indisputable fact that there are more and more female violin/cello players. That a significant proportion of the few soloists we see are women is entirely coincidental. Not worth mentioning.
