Generally, people who play well will not exclude you from playing. Of course, there are also some people who think too highly of themselves and are arrogant. See if you can solve it yourself. Don't be shy, just overcome a difficulty. Communicating with experts more is a good way to improve your skills.
If you really can't do it, you can actually practice alone. You can find a wall to hit, or buy a tied tennis backboard to help you practice, so you don't have to think about dealing with others. However, you may not feel the fun of tennis.
Besides, don't you have tennis lessons? There must be some students who are not very good at playing, right? You don't communicate with experts, but you can communicate with people at your level. Promote each other ~
As for the problem of not finding a venue, it can't be solved. After all, tennis is not particularly popular in China. You can play doubles, and let several people play together in one venue.
Wish you success! ! ~
